fixing build

Implemented inactivity timer that auto-closes Live Activity after 10 seconds without updates.

How it works:
- Timer starts when Live Activity is created
- Every update resets the timer back to 10 seconds
- If no updates received for 10 seconds, Live Activity auto-closes
- Timer uses RunLoop.common mode to work in background

This handles scenarios:
✓ App crashes or loses connection → auto-closes after 10 seconds
✓ Bluetooth disconnects → auto-closes after 10 seconds
✓ App in background continues workout → keeps updating, stays open
✓ Normal workout stop → closes immediately via explicit endActivity()

LIMITATION - Force-kill from app switcher:
When user force-kills app from app switcher, iOS terminates the process immediately.
No code can execute, including timers. In this case:
- Live Activity will NOT auto-close (iOS limitation)
- Stale date (15 seconds) will mark it visually as outdated
- User must manually dismiss from Lock Screen/Dynamic Island

This is still a major improvement: handles crashes, disconnections, and normal termination.
Force-kill scenario would require push notifications from a backend server to fix completely.
