f8ab0a7dc0 Fix restore-path main↔bleQueue deadlock and courier drop amplification (#1425)
* Fix restore-path main↔bleQueue deadlock and courier drop amplification

A device froze permanently in a two-phone test. Debugger stacks showed an
ABBA deadlock: the main actor was in bleQueue.sync (delivery-ack send →
broadcastPacket → readLinkState) while bleQueue was in main.sync
(captureBluetoothStatus reading backgroundTimeRemaining). The load that
lined the two edges up came from a courier-drop amplification storm:
drop dedup was in-memory only while the outbox driving 120s re-deposits
is persisted, so every relaunch republished the same undelivered DM as a
fresh 24h relay drop and every gateway relaunch re-fetched the whole
backlog — ~20 copies of one DM delivered in 40ms, each triggering
decrypt + delivery + ack + handshake work.

Fixes, in rank order:
- Edge B (P0): captureBluetoothStatus no longer main.syncs from bleQueue;
  backgroundTimeRemaining is sampled on main and cached behind a lock.
  Invariant documented: bleQueue must NEVER sync-dispatch to main.
- Edge A (P0, defense in depth): sendDeliveryAck / sendReadReceipt /
  sendPrivateMessage / sendNoisePayload / triggerHandshake hop to
  messageQueue like sendMessage, so no main-actor call path reaches
  readLinkState's bleQueue.sync.
- Drop dedup (P1): publishedDropKeys and seenDropEventIDs persist across
  relaunches (new BridgeDropDedupStore, entries expire with the 24h
  NIP-40 drop window; wiped on panic) — one drop per message ID per 24h
  regardless of relaunch count.
- Receiver dedup (P1): openCourierEnvelope dedups on the inner private
  message ID before delivery, so a duplicate copy costs one decrypt and
  never re-delivers, re-acks, or re-triggers a handshake.
- Handshake gating (P2): queued acks initiate a Noise handshake only for
  reachable peers; mail from absent/rotated identities no longer turns
  each copy into a mesh-wide handshake flood (the ack stays queued and
  flushes when a session eventually establishes).
- Outbox (P3): re-enqueueing a queued message ID carries over its
  depositedCourierKeys so resends stop re-burning the same courier slots.

* Review fixes: offline-drop durability, gateway handoff retry, restore-log freshness, coalesced persist

Adversarial review of the storm/deadlock PR surfaced four issues:

- Offline blackhole (must-fix): a deposit made while relays were down
  persisted its dedup key even though the drop only sat in the in-memory
  pending queue — app killed before reconnect meant the relaunch lost the
  drop but the persisted key blocked every re-deposit for 24h. The
  persisted snapshot now excludes keys still pending; they become durable
  only when flushPendingDrops actually publishes them.
- Gateway handoff: seen-event IDs were consumed before the deliverToPeer
  handoff; a failed handoff (peer walked away) permanently dropped the
  event for a single-gateway island. deliverToPeer now reports whether
  the handoff was attempted, and a failure releases the seen slot so a
  relaunch or backlog redelivery retries.
- Restore-path logs: central/peripheral-restore captures logged the init
  sentinel bgRemaining=∞. The cache is now seeded in init's main-thread
  branch and restore captures route through the sampler, which refreshes
  the cached budget before logging.
- Persist cost: the dedup record was a full JSON encode + atomic write on
  the main actor per mutation (once per event during a backlog re-fetch).
  Writes now coalesce behind a 1s window, flushed immediately on
  background/terminate; panic wipe stays immediate.

* Remove BoundedIDSet.remove, orphaned by the ExpiringIDSet migration

The drop-dedup sets that needed slot release moved to ExpiringIDSet;
remaining BoundedIDSet users only insert and check. Periphery caught it.

020de96519 Mesh bridging: stitch nearby mesh islands over the internet, courier drops, unified settings (#1412)
* Mesh bridging: stitch nearby mesh islands over Nostr, courier drops, settings surface

Three features plus a UI consolidation, all opt-in behind a new Bridge toggle:

Channel bridge: while bridging, outgoing public mesh messages are also
signed (with a derived, unlinkable per-cell Nostr identity) as kind-20000
events tagged #r with the local geohash-6 cell and published to the cell's
deterministic geo relays; mesh-only peers deposit via new toBridge/fromBridge
carrier directions through a bridge gateway (bridge + gateway toggles).
Remote islands' events render into the mesh timeline marked with a network
glyph. Events carry the original mesh message ID so the store's insert-by-ID
absorbs radio/bridge duplicates in either order. Loop prevention mirrors
GatewayService (three BoundedIDSet caches + skip-if-seen-locally + budgets).
Nothing crosses a bridge unless its author signed it for the bridge; a
per-message "nearby only" composer toggle keeps a message radio-only.

Courier over the bridge: sealed courier envelopes park on default relays as
kind-1401 drops tagged #x with their day-rotating recipient tag (NIP-40
expiry), signed by per-drop throwaway keys. Recipients subscribe for their
own candidate tags; bridge gateways watch verified local peers' tags and
hand matching drops over as directed courier packets. DM delivery to known
peers stops requiring a physical courier encounter; the Noise-X seal never
opens in transit.

Presence: kind-20001 heartbeats on the rendezvous feed a "people across the
bridge" count in the header (approximate: local participants subtracted by
radio-copy attribution).

Settings/Info: AppInfoView is now a segmented Settings/Info sheet. Settings
hosts appearance, voice (fixes the duplicated Voice section), a Connectivity
section (bridge + gateway + Tor toggles, the latter two moved out of the
location sheet), and a confirmed panic-wipe button. New announce TLV 0x06
advertises the gateway's rendezvous cell; PeerCapabilities gains .bridge.

i18n: 23 new keys across all 29 locales; coverage tests green.
Tests: 50 new app tests + 3 BitFoundation tests; full suite 1445 green.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Settings polish: one toggle style, sticky Info-first tab, location access in Settings

- The live-voice toggle now uses the same settings card + IRC pill as the
  connectivity toggles (settingToggle, renamed from connectivityToggle).
- Segmented control orders Info first; the selected pane persists across
  opens (AppStorage), so first-ever open lands on Info and afterwards the
  sheet reopens where it was left.
- "remove location access" moved from the channels sheet into the Settings
  Connectivity section (same key, still deep-links to system settings).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Location UX + copy: state-aware access control, honest empty state, clearer bridge/gateway text

- Settings' location control now covers all three permission states: grant
  (real prompt, only possible while never-asked), open-system-settings when
  denied, remove-access when granted. The channels sheet keeps its own grant
  path for people who start there.
- The channels list no longer spins forever without permission; it shows
  "grant location access to find nearby channels" instead (new key, 29
  locales).
- Bridge and gateway subtitles rewritten for clarity; the gateway subtitle
  moved to a new key since it now carries bridge traffic, and the old
  geohash-only key is deleted. The word "user" is banned from copy in every
  locale ("this person is blocked").

* Field-test fixes: dedupe relay-connectivity triggers, throttle presence, log bridge decisions

First on-device run confirmed publishes accepted and the subscription
delivering, but exposed trigger spam: NostrRelayManager's isConnected
re-emits per relay recompute, so presence published 5x/second and the
courier-drop subscription rebuilt 6x in 300ms. removeDuplicates() on the
sinks + a 30s presence throttle (same-second heartbeats are byte-identical
events anyway). Also: injection/skip/downlink now log under 🌉 so field
verification is observable — the first test looked silent precisely because
dedup correctly suppressed same-island bridged copies.

* Fix restart self-echo: recognize own rendezvous events by derived pubkey

Second field run proved bidirectional bridging live (~1-2s Mac<->iPhone via
Tor) but caught a bug: relay backfill after an app relaunch re-delivered the
device's own pre-restart events, and with the in-memory published-ID cache
wiped they rendered as bridged copies of your own messages. The rendezvous
identity is deterministically derived per cell, so self-recognition by
pubkey needs no cache and survives restarts; own events are also marked
never-downlink. Regression test simulates the fresh-launch state.

* People sheet: mesh, bridge, and groups in one list

The header's bridged count had no matching faces anywhere — the people
sheet only knew mesh peers. BridgeService now publishes named participants
(nickname from message tags, geohash-style #last4 disambiguation, presence
keeps a known name alive) and the mesh people sheet gains an
"across the bridge" section between mesh peers and groups. Display-only
rows in v1 (bridged identities have no DM route yet). Two new catalog keys
x29 locales; also normalizes one out-of-sort-order entry inherited from a
hand-edited key on main.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Header: one people icon, one count, one sheet

Fold the bridged-people count into the main person.2.fill count instead of
a second network-glyph counter; the merged people sheet (mesh / across the
bridge / groups) is the breakdown. VoiceOver still announces how many of
the total are across the bridge.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet symmetry: #mesh section header, no active count

Every section now gets the same glyph+label header shape (shared
PeopleSectionHeader): #mesh over the peer list, across-the-bridge over
bridged people. The "N active" line is gone (mesh); location channels keep
their geohash subtitle. Dead subtitle/count helpers removed.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* One switch: the bridge toggle drives all internet sharing

Field feedback: two toggles (bridge + gateway) with an invisible dependency
was a trap — bridged messages silently never reached mesh-only neighbors
unless a second lever was found and flipped. Collapsed to a single switch
that does the right thing for your situation:

- Bridge ON + internet: your messages cross, you see the bridge, AND your
  device serves its island — accepts toBridge deposits, carries remote
  messages onto the radio, watches courier drops for verified local peers,
  advertises the cell, and runs the geohash-channel gateway.
- Bridge ON, no internet: you ride whoever nearby is serving.
- Bridge OFF: nothing of yours crosses; radio reception of bridged traffic
  stays passive and free.

With every online bridger serving, downlink gets a 0.2-1.5s jittered
holdoff + send-time suppression recheck so co-located gateways don't burn
duplicate airtime (two-gateway test included). The internet-gateway card is
gone from Settings (GatewayService now follows the bridge switch, with
launch-time migration); its orphaned catalog keys deleted and the bridge
subtitle broadened across all 29 locales. Also: MeshPeerList's empty state
("nobody around...") aligned to the section row rhythm.

* Bridge pumps its own location; fix centered people sheet; stop drop-subscription churn

Field session 3 found the bridge silently cell-less: it read
availableChannels passively, which only flow while some other feature
(channels sheet, location notes, geo sampling) happens to pump location —
turn those off and the bridge never gets a rendezvous. BridgeService now
requests a one-shot fix whenever it's enabled without a cell (and
piggybacks one on the presence timer so moving devices migrate cells).

Also from the session: the people sheet's scroll content hugged its widest
child and got centered on iPhone when the list was empty — pinned to full
width, leading. And the courier-drop subscription rebuilt every ~60s on
verified announces despite an unchanged tag set — now resubscribes only
when the tags actually change.

(Also merges origin/main: keychain test isolation #1413.)

* Fix launch race: bridge reacts to the permission callback, retries cell-less

Field session 4: the launch-time location request ran before the CoreLocation
authorization callback delivered, so refreshChannels() silently no-opped
(it requires .authorized) and nothing ever retried — the bridge stayed
cell-less all session. Three layers now close it:

- a $permissionState sink re-enters refreshRendezvous the moment
  authorization resolves (the fast path),
- the maintenance timer arms even without a cell and retries the full
  rendezvous refresh (the backstop; it previously required a cell, which
  made it useless for exactly this failure),
- flipping the bridge switch while never-asked triggers the location
  prompt — that's the user-initiated moment for it.

* People sheet: one header style for every section; bridged people visible while own bridge is off

GroupChatList's header now uses the shared PeopleSectionHeader (glyph +
label, same size/padding as #mesh and across-the-bridge; keeps its key and
header trait). Bridge section and the header count are no longer gated on
this device's own toggle: bridged people arrive over passive radio from a
serving neighbor, and whoever is visible in the timeline belongs in the
sheet and the count.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: equalize the first section's gap

MeshPeerList's first row kept a legacy 10pt top bump from when nothing sat
above it, and the outer VStack's 6pt inter-child spacing applied between
the #mesh header and the list but not inside the other sections. Both gone:
sections own their rhythm (header 12/4, rows 4), spacing 0 outside.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: rows drop their leading glyphs — the section header carries the type

Mesh rows lose the per-state transport icon (connected/relayed/nostr/
offline), bridge rows the network glyph, group rows the person.3 icon.
Trailing state badges (star, lock, verified, unread, blocked, crown) stay,
and the row accessibility description still announces connection state, so
VoiceOver loses nothing.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Remove dead code left behind by the Settings|Info consolidation

Periphery (--strict) flagged five leftovers on this branch:
- LocationChannelsModel.setGatewayEnabled: the standalone internet-gateway
  toggle is gone (the bridge switch drives internet sharing), so nothing
  calls it; the gatewayEnabled published property stays for the header dot.
- AppInfoView Strings.Location title/enable/openSettings: the old Location
  section's header and permission buttons no longer exist. Their orphaned
  Localizable.xcstrings entries go with them (the gateway-toggle keys were
  already pruned).
- BridgePeopleList's appTheme environment value was never read.

The sixth CI finding (PrekeyBundleStore.StoredBundle.noiseKey assign-only)
is a Periphery flake: the property is read in loadFromDisk, the finding
didn't reproduce locally or on the next CI run of unchanged code.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* People sheet: mesh rows get their transport glyph back

The mesh section is the one heterogeneous list — the leading icon encodes
HOW a peer is reachable (radio / relayed / nostr-only / offline), which the
header can't say. Bridge and group rows stay glyph-free.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Fix courier drop skipped by stale BLE reachability; periodic deposit sweep

Field test: a DM sent seconds after the recipient's radio vanished still
saw them as "reachable" (60s verified retention), so canDeliverPromptly
held, every deposit was skipped, and the message sat spooled with no retry
path. MessageRouter now sweeps its outbox every 2 minutes and publishes
bridge drops for messages whose recipient no transport can promptly reach;
the drop layer's message-ID dedup makes the sweep idempotent. Regression
test reproduces the exact field sequence.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Show "carried" when a message ships as a bridge drop

Field feedback: dropped DMs delivered but the sender saw nothing — the
drop path never fired onMessageCarried, and the recipient's delivery ack
has no radio route back until the peers next share a transport. depositDrop
now reports whether a fresh drop was sealed and the router marks the
message carried (📦) on both the send path and the sweep; the ack still
upgrades it to delivered whenever a route exists.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Fix locale word order: offline tag after name in DM header; localized "ago"

The private-chat header rendered the localized offline word in the
availability-glyph slot, before the name — "sin conexión bob". Offline now
shows the same dimmed person glyph the mesh list uses, with the word as a
small trailing tag after the name and lock, so it reads correctly in every
locale. Full sweep of views found one more composition bug: notice
timestamps glued English "ago" onto a localized duration; now the whole
phrase comes from RelativeDateTimeFormatter (same as the "fades" label).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* DM header offline state: icon only

The availability slot now reads uniformly as a glyph (radio / relayed /
globe / dimmed person), matching the mesh list; the text tag is gone.
VoiceOver still announces "offline" via the glyph's accessibility label.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Offline glyph: slashed antenna instead of dimmed person

Offline is now the visual negation of connected (same antenna glyph,
slashed) in both the DM header and mesh list rows; a generic person icon
didn't say "unreachable".

ef848857b7 Remove dead code found by full Periphery audit; add scan config + advisory CI (#1410)
Periphery 3.7.4 audit of both schemes (macOS + iOS, intersected so
platform-specific code is never touched), with test targets indexed and
the share extension built. 277 dead declarations removed or demoted:
dead forwarding wrappers (ChatViewModel+Nostr/+PrivateChat), removed-
feature remnants (autocomplete command suggestions, back-swipe tuning,
MediaSendError, GeohashParticipantTracker), unused Tor dormancy
bindings, assign-only properties, unused parameters (renamed to _), and
redundant public accessibility. 13 orphaned localization keys deleted
across all 29 locales (old pre-#1392 location-notes UI, app_info
warnings).

Two real tests were flagged as unused because they never ran: Swift
Testing methods missing @Test (NostrProtocolTests.
testAckRoundTripNIP44V2_Delivered, NotificationStreamAssemblerTests.
testAssemblesCompressedLargeFrame). Re-armed both; they pass.

Deliberately kept, now recorded in .periphery.baseline.json: iOS-only
code invisible to the CI macOS scan, C FFI signatures, keep-alive
NWPathMonitor reference, InboundEventKey.eventID (dedup semantics),
wifiBulk capability bit (reserved for Wi-Fi bulk work, used by
BitFoundation package tests), and the String secureClear cluster
(exercised by package tests).

New: .periphery.yml config and an advisory Dead Code CI job (mirrors
the SwiftLint precedent from #1361) that fails on findings not in the
committed baseline.

Verified: full macOS app suite, BitFoundation (119) and BitLogger (13)
package tests green; periphery scan --strict exits clean.

7341696280 Expand store-and-forward: open couriers, spray-and-wait, persistent outbox, 6h public history (#1372)
Store-and-forward previously delivered to an out-of-range peer only if a
mutual favorite happened to be connected at send time and later met the
recipient directly, and everything except courier envelopes died with the
app process. This closes those gaps end to end:

- Persist the MessageRouter outbox to disk, sealed with a ChaChaPoly key
  held only in the Keychain (no plaintext at rest); queued private
  messages now survive an app kill and flush on next launch.
- Deposit retry: queued messages are re-deposited whenever a new eligible
  courier connects, tracked per message so the same courier is never
  double-burned, until 3 distinct couriers carry it or it expires.
- Tiered open couriering: signature-verified strangers can now carry mail
  (2 envelopes/depositor into a 20-slot pool) alongside mutual favorites
  (5 each); overflow evicts verified-tier mail before favorites'.
- Spray-and-wait: envelopes carry a copy budget (4, capped 8, new TLV,
  wire-compatible with old clients); couriers split half their remaining
  budget with each newly encountered courier so mail diffuses through a
  moving crowd.
- Remote handover: a verified relayed announce now floods a copy toward
  the multi-hop recipient (directed-relay treatment, 10-min per-envelope
  cooldown) while the carried original stays put for a direct encounter.
- Public history: gossip-sync window for whole public messages widened
  from 15 min to 6 h, matched on the receive-acceptance side, and the
  message store persists to disk so devices bridge partitions and
  restarts ("town crier").
- Privacy-safe local delivery counters (bare tallies, log-only) so the
  store-and-forward stack is measurable on-device.
- Panic wipe now also clears the sealed outbox, gossip archive, and
  counters.
- Rewrite WHITEPAPER.md to describe the app as implemented (Noise XX/X,
  actual flood control, courier system, gossip sync, Nostr path); the old
  document described a bloom filter, three fragment types, and a
  MessageRetryService that don't exist.

1037 macOS tests pass (17 new); iOS builds.

a66c591f8e Courier: deposit in parallel when the only route is a send queue (#1368)
* Deposit with couriers in parallel when the only route is a send queue

The courier path was nearly unreachable: NostrTransport claims any
favorite with a known npub as "reachable" regardless of connectivity,
and the mesh favorite exchange shares npubs, so for essentially every
courier-eligible recipient the router picked Nostr's reachable branch.
With no internet the message just sat in the relay send queue — in the
flagship scenario (internet shutdown, mutual friend standing right
there) the courier walked away carrying nothing.

Add Transport.canDeliverPromptly(to:), defaulting to reachability for
radio-backed transports; NostrTransport answers honestly by mirroring
the relay manager's connection state (fail-closed behind Tor). When the
chosen transport can't hand the message off promptly, the router now
also deposits a sealed copy with connected couriers. Double delivery is
harmless: receivers dedup by message ID, and delivered/read acks never
downgrade the carried status. When relays are up, sends are trusted and
no courier quota is spent.

* Track DM-relay connectivity, not any-relay, for prompt delivery

Codex review: NostrRelayManager.isConnected is true when any relay is
up, including geohash/custom relays — but private messages target the
default (gift-wrap-capable) relay set and queue when none of those are
connected. A lone geohash relay would have suppressed the parallel
courier deposit while the DM sat in the queue. Publish a DM-scoped
connectivity flag and drive canDeliverPromptly from it.

75da63c9d7 Fix favorites end-to-end: peer-list duplicates, Nostr sync, /fav key corruption (v1.5.4) (#1367)
* Friend-courier store-and-forward: mutual favorites carry sealed messages to offline peers

When a private message has no reachable transport, the router now seals it
to the recipient's Noise static key (new one-way Noise X pattern) and hands
the envelope to up to three connected mutual favorites. Couriers store the
opaque ciphertext under strict quotas (20 total, 5 per depositor, 16 KiB,
24 h) and hand it over when the recipient's announce matches a rotating
HMAC recipient tag; the recipient opens it and the message flows through
the normal private-message pipeline, so dedup and delivery acks just work.

- CourierEnvelope TLV + courierEnvelope (0x04) message type in BitFoundation
- Noise X one-way pattern reusing the existing handshake machinery,
  domain-separated by a courier prologue; sender identity authenticated
  via the ss DH (no forward secrecy - documented tradeoff)
- CourierStore with eviction, file persistence, and panic-wipe integration
- Rotating recipient tags (HMAC over epoch day) so carried envelopes don't
  correlate for observers who don't already know the recipient's key
- New "carried" delivery status with figure.walk glyph; header indicator
  while carrying mail for others
- Three-node end-to-end test ferrying packets through real BLEService
  instances, plus codec/crypto/store/router suites (986 tests green)

* Fix courier handoff verification and directed sends

* Authenticate courier deposits by ingress peer

* Gate courier handover on direct announces and isolate store test

Envelopes are removed from the courier store optimistically, so releasing
them on a relayed (multi-hop) announce risks losing carried mail to a
speculative flood that never reaches the recipient. Handover now also
requires the announce to have arrived directly (full TTL), i.e. an actual
encounter with a live link; regression test builds a relayed copy of a
genuinely signed announce (TTL is excluded from announce signatures).

Also make CourierStore's on-disk location injectable so the persistence
test round-trips through a temp directory instead of wiping the real
Application Support store, and reattach BLEAnnounceHandler's doc comment
to the class it describes.

* Use Xcode-bundled Swift in CI instead of a standalone toolchain

The unpinned setup-swift action installs Swift 6.1, which refuses the
SDK on runner images that have rolled to Xcode 26.5 ("this SDK is not
supported by the compiler"). Jobs passed or failed depending on which
image they landed on. The Xcode-bundled toolchain always matches the
image's SDK, and matches local development. Cache keys now include the
toolchain version so artifacts from one compiler are never restored
into builds with another.

* Drop couriered mail from blocked senders at envelope open

The UI-layer block check (isPeerBlocked in the transport event
coordinator) resolves a fingerprint from the live session or peer list,
but a couriered message arrives precisely when its sender is absent —
no session, no registry entry — so the check failed open and a blocked
identity's mail was delivered anyway. Gate in openCourierEnvelope,
where the sealed sender's full static key is in hand.

End-to-end test ferries a full deposit→carry→handover round and
verifies the envelope from a blocked sender never reaches the delegate
(confirmed failing without the gate).

* Fix favorites end-to-end: peer-list dedup, Nostr sync, /fav key corruption

- UnifiedPeerService: dedup offline favorites against mesh peers by noise
  key. Phase 2 compared a 64-hex noise-key PeerID against 16-hex mesh IDs
  (never equal), leaving only a nickname+isConnected heuristic — a mutual
  favorite that was reachable-but-not-connected or renamed rendered twice,
  and a same-nick stranger could suppress a favorite entirely.
- Nostr inbound: intercept [FAVORITED]/[UNFAVORITED] markers in the live
  PM handler so they update theyFavoritedUs instead of rendering as chat
  text; mutual favorites can now form over Nostr. Delete the dead
  favorite-aware PM variant and ChatNostrCoordinator.handleFavoriteNotification
  (unwired, parsed a stale FAVORITE:TRUE|… format no sender emits).
- NostrTransport.isPeerReachable: match short form regardless of incoming
  ID width — toggling an offline favorite (addressed by 64-hex noise key)
  was silently dropped with no reachable transport.
- BLEService.sendPrivateMessage: normalize recipient to the short ID like
  sendFilePrivate, so a 64-hex target hits the existing Noise session
  instead of initiating a handshake with a 32-byte wire recipient ID.
- /fav, /unfav: stop writing Data(hexString: peerID.id) — the 8-byte
  routing ID for mesh peers — into the favorites store as a "noise key",
  and stop double-sending the favorite notification; delegate to
  toggleFavorite with a proper state check.
- FavoritesPersistenceService.updatePeerFavoritedUs: keep the stored
  nickname when the caller passes the "Unknown" placeholder.
- Bump marketing version to 1.5.4.

* Route DMs to mutual favorites via Nostr when a mesh-keyed peer goes offline

Field-tested on device: with a DM window opened while the peer was on
mesh (conversation keyed by the short 16-hex ID), walking out of range
and sending failed instantly with "peer not reachable" even though the
header showed the peer as Nostr-reachable (mutual favorite, npub known).

sendPrivateMessage derived the favorites key as Data(hexString:
peerID.id) — for a short mesh ID that is the 8-byte routing ID, never
the noise key — so the mutual-favorite/Nostr-key checks always came up
empty and the send failed before reaching MessageRouter. Conversations
keyed by the full 64-hex noise-key ID (opened from the offline favorite
row) were unaffected, which is why later tests appeared to work.

Resolve the noise key properly (peerID.noiseKey, then the unified peer
row, then the favorites store by derived short ID) and add a regression
test for the mesh-keyed-peer-goes-offline case.

* Label Nostr DMs from favorites with their stored nickname

Field-tested: a DM delivered over the Nostr fallback rendered as
"anon#678e" instead of the sender's name. The inbound handler named the
sender via displayNameForNostrPubkey, which only knows geohash-scoped
names — even though the pipeline had already resolved the sender's
noise key (the conversation is keyed by it).

When the conversation key carries a noise key, prefer the favorite's
stored nickname; geohash DMs (nostr_ keys) keep the anon geo name. This
also stops an inbound Nostr [FAVORITED] from overwriting the stored
nickname with the anon fallback, since the same name feeds
updatePeerFavoritedUs.

* Fix courier path for offline favorites addressed by noise-key IDs

Two Codex review findings, both the same ID-width confusion this PR
targets, in the courier flow:

- CourierDirectory.favoritesBacked resolved recipients only via
  getFavoriteStatus(forPeerID:), which requires a short 16-hex ID —
  offline favorites are addressed by the full 64-hex noise-key ID, so
  attemptCourierDeposit silently bailed for exactly the peers couriers
  exist to serve. The 64-hex ID now yields its own key directly.
- openCourierEnvelope emitted the derived short mesh ID even when the
  sender has no live mesh identity, landing couriered mail in an
  unresolvable short-ID thread labeled "Unknown". Absent senders now
  emit the full noise-key ID so the message joins the stable favorite
  conversation; present senders keep the live short-ID thread.
