forceStop method
Force-stops the client immediately without graceful session cleanup.
Unlike stop, this does not attempt to destroy sessions via RPC. It clears sessions, kills the connection, and closes the transport.
Implementation
Future<void> forceStop() async {
_forceStopping = true;
_sessions.clear();
_modelsCache = null;
await _connection?.close();
_connection = null;
await _transport?.close();
_setConnectionState(ConnectionState.disconnected);
}
