Michael Neale cc9b0b22c4 refactor(serverless): back agent relay layer with nostr-relay-pool
The serverless agent path hand-rolled multi-relay subscribe/reconnect/
resubscribe/dedup in relay.rs — reimplementing what nostr-relay-pool
(rust-nostr) already does, with gaps that caused the agent to miss
messages when a single relay 502'd mid-session.

Replace the serverless backend with nostr-relay-pool's RelayPool, which
provides the standard Nostr client model used by damus/0xchat/nostr-tools:
- persistent REQ per relay, fanned out across all relays
- auto-reconnect (default) with jittered backoff
- auto-resubscribe on reconnect (relays replay stored events on REQ)
- merge + dedup across relays (Event notification = first-seen only)

HarnessRelay now dispatches to ServerlessRelay when serverless; server
mode (NIP-42 AUTH + HTTP bridge) is unchanged. RestClient and the typing/
presence publisher share the pool. Subscription IDs match the server-mode
scheme so event routing is identical.

Proven: e2e_agent_responds passes 3x consecutively (~3s each) against live
public relays, surviving damus 503s via nos.lol.

- 272 unit tests pass, clippy clean
