- Fix: CONNECT/RETRY_CONNECT always force-disconnect before reconnecting
(prevents JOIN_ROOM going to official server when custom is selected)
- Add forceDisconnect() helper: clears socket, eventQueue, episodeLobby,
expectedAcksCount, broadcast status, persists cleanup to storage
- Fix: save useCustomServer to storage on Join Room click (no race condition)
- Fix: trigger RETRY_CONNECT on server mode toggle and custom URL change
- Fix: show error when Custom selected but no URL entered (no silent fallback)
- Fix: button label changed to 'Join / Create Room' in all 6 locales
- Rewrite scheduleReconnect() for two-phase strategy:
Phase 1 (aggressive): 500ms-5s backoff, max 20 attempts or 5 minutes
Phase 2 (slow): retry every 5 minutes indefinitely, never give up
- Persist reconnectAttempts/reconnectStartTime/reconnectFailed to session storage
- Remove 'reconnect_failed' status; slow mode shows as 'reconnecting' with retry button
- Add scheduleReconnect() call on offline path to continue retry cycle
