Module manager 

Current-room registry and lifecycle coordinator.

RoomManager publishes one current room per issuer, admits WebSocket sessions and runs background room work. Mutations acquire a lifecycle lease without holding the directory lock. Empty-room removal waits for every accepted lease to finish.
