Address two review findings on the Tor egress self-check:
1. Bypass on the already-bootstrapped path: shouldWaitForTorBeforeConnecting
only checked torIsReady, so once Tor was up, connectToRelays/connectToRelay
(initial connect, reconnect backoff timers, manual retry, subscription-
triggered connects) opened relay WebSockets without ever running the egress
canary. The gate now also requires a fresh cached egress verification
(TorManager.isEgressVerified, backed by a nonisolated TTL snapshot on
TorEgressVerifier); any path lacking one queues behind awaitEgressReady().
2. unreachable canary no longer allows: an unreachable canary is exactly the
ambiguous case where we cannot tell whether the platform honored the SOCKS
proxy, so it now refuses relay connections (fail-closed) instead of
allow-with-warning. A verifiedTor verdict still allows connection opens for
its 300s TTL (a cached good verdict covers brief canary blips); after TTL
expiry or invalidate() (Tor restart/dormant/shutdown) connections stay
closed until a probe succeeds again. Probe cadence stays bounded via the
verifier's minRetryInterval, and the relay manager schedules a bounded
30s-cadence gate retry after wait-attempt exhaustion so a transient canary
outage recovers automatically (GeoRelayDirectory already retries with its
own backoff).
Tests: verifier policy (unreachable refuses, recovery via retry, cached-
within-TTL allows during blip, TTL expiry + unreachable refuses, snapshot
invalidation) and relay-manager gating (ready path awaits egress verification,
reconnect requeues behind the gate, exhaustion schedules the bounded retry and
recovers).

Runtime-verified whether Apple's URLSession honors connectionProxyDictionary
SOCKS settings for Nostr relay traffic (plain HTTPS + URLSessionWebSocketTask),
since the app routes all Nostr traffic through Arti's local SOCKS5 proxy solely
via those keys and Apple does not officially support SOCKS for URLSession on iOS.
Verification harness (scripts/tor-egress-verification/): a minimal SOCKS5 CONNECT
proxy that logs arriving connections, plus a Swift probe that runs an HTTPS GET
and a WebSocket ping through a URLSession configured with the proxy dict. Result:
on macOS (kCFNetworkProxiesSOCKS* constants) and the iOS simulator (raw
"SOCKSProxy"/"SOCKSPort" string keys, the exact app path) BOTH HTTP and WebSocket
are proxied, do remote DNS through the proxy, and the proxied session is
fail-closed (every request errors when the SOCKS proxy is down). The feared
direct-egress leak did not reproduce on the tested platforms.
Defense-in-depth for the platform Apple does not guarantee (physical iOS):
add TorEgressVerifier, which performs a canary request through the proxied
session and asserts the exit is a Tor node (check.torproject.org IsTor==true),
positively detecting a direct egress even if the OS silently ignored the proxy.
Policy: verifiedTor allows (cached for a TTL); notTor refuses (leak detected,
never open relays); unreachable allows-with-warning (session stays fail-closed
by construction). Wired into TorManager.awaitEgressReady() and required by both
NostrRelayManager and GeoRelayDirectory before opening connections. Cache is
invalidated on Tor restart/dormant/shutdown. Never falls back to a direct
connection.
Probe is injected so the policy/caching is unit-tested offline; the live-network
harness lives under scripts/ and is not run by CI.

* 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.
