feat: Add track command to log time to task manager

Add new 'track' command that:
- Stops the current timer
- Executes 'task add +track "Xmin DESCRIPTION"'
- Resets the timer on successful task creation
- Preserves timer state if task creation fails

This allows seamless integration with taskwarrior for time tracking.
