- Rooms\Room + Rooms\RoomManager: track peers per room, auto-mesh a new joiner
with everyone already there, drop empty rooms
- SignalingHandler: join/leave message types (auto-connectPeers on join), and
close now also leaves the room; expose rooms()
- SignalingServer::address() for the bound listen address
- Tests: real offer->answer round-trip over a live TCP socket on the kernel loop,
RoomManager + join/leave/close coverage. Suite: 17 tests / 42 assertions
- Verified on the updated reactphp-kernel (logging + registry)
