Phase 884: gossip RPC pull opts, payload builders, search responders extract (v0.8.851)

Non-breaking refactor: buildGuildGossipRpcPullOpts() for config+override assembly;
extend payload builders for host sync, member page, and message search pulls;
registry lookup helpers; extract message search RPC responders; unify all pull
mixins on shared opts builder. Default gossip v1 unchanged; fleet v2 cutover
still deferred.
