Fail closed on unverified egress and gate the already-ready connect path

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).

+/// TTL / retry semantics:
+///   - A `verifiedTor` verdict allows connection *opens* for `ttl` without
+///     re-probing, so a brief canary blip inside the TTL window does not take
+///     relays offline (a fresh positive verdict is authoritative for the
+///     window). Already-open sockets are never torn down by verification —
+///     they were opened under a verified egress and the proxied session is
+///     fail-closed by construction.
+///   - After TTL expiry (or `invalidate()` on Tor restart/dormant/shutdown),
+///     the next `verify()` re-probes; while the canary stays `.unreachable`,
+///     new connection opens are refused until a probe succeeds again.
+///   - Probe cadence is bounded: at most one probe per `minRetryInterval`
+///     (callers within the window reuse the last decision), and concurrent
+///     `verify()` calls share one in-flight probe. Recovery from a transient
+///     canary outage is automatic: callers that keep retrying (relay connect
+///     gate, GeoRelayDirectory backoff) re-probe and succeed once the canary
+///     is reachable again.
 ///
 /// The probe is injectable so the policy/caching logic is unit-tested without a
 /// live network (see `TorEgressVerifierTests`).
