Chess game scene:
- Imports and calls matchLive.start(matchId, 'chess', callbacks)
- Creates localStorage entry → browser refresh auto-resumes
- matchLive.session.destroy() on endGame → clears recovery

Ludo game scene:
- Same pattern: matchLive.start(matchId, 'ludo', callbacks)
- Clears session on endGame

Now the flow works:
1. Player enters live game → matchLive.start() saves to localStorage
2. Player refreshes browser → engine boot finds recovery → verifies server → auto-rejoins
3. Game ends normally → matchLive.session.destroy() clears localStorage
4. Player goes to homepage after game → no recovery popup (correct)
