Fixes modelcontextprotocol#4710. The subscriptions Map retained sessionIds after disconnect because cleanup() only cleared intervals and task store. Export removeSubscriber(sessionId) that iterates the map, deletes the session from each Set and drops empty entries, and call it from server factory cleanup() (used by streamableHttp and sse onclose). The reference server is the example clients copy; this prevents unbounded growth from clients that subscribe then disconnect without unsubscribing.
