* NIP-13 proof-of-work for geohash channels: mine on send, relax rate limits for PoW senders
Outgoing kind-20000 geohash messages mine a NIP-13 nonce tag (8 leading
zero bits, ~256 hashes, typically <1 ms) off the main actor before
signing. Mining is hard-capped at 2 s and cancellable (newer send or
channel switch): on cap/cancel the committed target steps down so the
message still ships promptly with an honest commitment - sending is
never blocked and nothing is dropped. The hot loop serializes the
canonical event once and rewrites only the fixed-width nonce bytes.
Inbound kind-20000 events are scored per NIP-13 commitment semantics
(committed target counts; the ID must actually meet it, extra work
earns nothing) and never hard-rejected: validated PoW >= 8 bits skips
the per-sender rate-limit bucket while the per-content flood bucket
still applies, so old non-mining clients keep working under today's
strict limits while bulk spam gets expensive.
Presence heartbeats (kind 20001), kind-1 notes, and DMs are unchanged;
no UI beyond a pow= field in an existing sampled debug log.
Reimplemented from scratch rather than cherry-picking the stale
feature/pow-geohash-mining-ui branch (unbounded loop, hard receive
filtering, mining UI, XCTest, force unwraps).

* Geohash: serialize PoW sends so order matches send order
Two location-channel sends back-to-back only cancelled the previous
mining task and started a new one. Cancellation merely *expedites* NIP-13
mining (the target is polled and steps down; it never aborts the send),
so the cancelled task still appended + relayed once mining returned. Both
tasks ran concurrently and the second (shorter to mine) could finish
first, reordering messages in the timeline and on relays.
Chain the mining tasks: each geohash send captures the previous send's
task, cancels it (to expedite, so delays never stack), and awaits its
completion before it echoes and relays. Order is now always send order.
The >2s mining cap is preserved: cancellation expedites the awaited task,
so a send is never blocked beyond NostrPoW.miningTimeCap.
Test: two rapid sends where the first mines longer (larger content) still
land in send order for both the local echo and the relayed events.

* Make location notes robust: durable relay subscriptions, failure decay, auto-recovery
Location notes (and geohash chat / DMs) intermittently stopped showing
events because the Nostr relay layer lost subscriptions and blacklisted
relays:
- Replay active subscriptions on every relay (re)connect. Relays drop
REQs with the socket; previously a drop silently killed the
subscription on that relay for the rest of the session. Durable
subscription intent now also survives disconnect()/resetAllConnections
(background -> foreground).
- Keep failed REQ sends queued instead of dropping them.
- Raise the EOSE fallback from a fixed 2s Timer to a 10s injected
schedule (Tor needs more than 2s), and settle EOSE trackers when a
relay disconnects before answering so initial load doesn't stall.
- Decay "permanently failed" relay markings after a 10-minute cooldown;
previously ~9 minutes of outage (or one DNS hiccup) excluded a relay
until app restart, with nothing resetting it on macOS.
- Make geo relay selection deterministic (distance, then host) so
publishers and subscribers with the same directory agree on relays.
- Post .geoRelayDirectoryDidRefresh after a directory fetch and let
LocationNotesManager auto-resubscribe out of the "no relays" state
instead of requiring a manual retry.

* Guard subscription activation on connection identity
A REQ send completion from a dead socket could land after
handleDisconnection cleared the relay's subscriptions and re-mark the
subscription active, making the next connection skip the durable replay
and leave that relay silent. Only mark a subscription active if the
completing socket is still the relay's live connection.
Regression test defers send completions in the mock so the stale
completion deterministically interleaves between disconnect and
reconnect.
Addresses Codex review on #1333.
