Add a revision-scoped ResidentSupervisor that serializes Host events through ResidentSession while Tokio tasks own timers, TCP listeners, and stream sockets.
Enforce deny-by-default endpoint policy, bounded event and stream queues, startup rollback, deterministic service shutdown, stale Actor replacement, and deployment restoration across Runtime restarts.
Add timer and real TCP integration coverage for port conflicts, multi-chunk echo traffic, service restart, and full Runtime recovery.
Add the versioned wasmeld:resident@0.1.0 event/effect contract for timers, streams, datagrams, messages, extension sources, and shutdown.
Add a resident-probe Component with locked service and resident WIT dependencies so the ABI can be built, packed, and exercised independently.
