Improve: Reduce notification interval from 2 hours to 10 minutes

- Changed notification interval from 2h to 10min for more responsive feedback
- Updated time calculation from hours to minutes
- High activity notifications now show every 10 minutes instead of 2 hours
- More suitable for active development sessions
- Users get timely reminders without waiting 2 hours

Testing:
- Verified notification shows after 11 minutes
- Confirmed suppression works within 10 minutes
- 174 operations tracked correctly
