Complete rewrite of qconnect.rs following desktop's
QconnectServiceState::connect() line by line:
1. Subscribe to transport events BEFORE bootstrap (was after)
2. Event loop checks InboundQueueServerEvent for SESSION_STATE
(was checking SessionManagementEvent via sink channel)
3. Forward events to handle_transport_event AFTER inspection
4. Bootstrap called AFTER event loop starts
5. Re-bootstrap on reconnect (Subscribed + has_disconnected)
The key bug: event loop was subscribing AFTER bootstrap, missing
the SESSION_STATE response. Desktop subscribes at line 1238,
bootstraps at line 1405.
