resetSession abstract method
Forcefully resets a stuck session.
On iOS this performs a full teardown: it removes the session manager
listener, cleans up the remote media client (listener, position timer,
queue), force-ends the current session, resets internal dedup state,
re-adds the listener, and emits a null session to Flutter so that
currentSessionStream, currentSession and connectionState are
cleared.
On Android this delegates to endSessionAndStopCasting because stale-session issues are not observed on that platform.
Implementation
Future<bool> resetSession();
