Sand Timer

Our app runs countdown timers in the background that need to continue
operating when the app is minimized or the screen is off. The foreground
service is essential for:

1. Maintaining accurate countdown timing while the app is in the background
2. Ensuring timer completion alarms trigger reliably
3. Displaying real-time timer progress in the notification
4. Playing alarm sounds when the timer completes

The timer service does not fit into standard foreground service types
(such as location, media playback, camera, etc.) as it is specifically
for time-based countdown functionality. This qualifies as a "special use"
foreground service under Android 14+ requirements.

User-facing feature:
Users set countdown timers and expect them to complete accurately even when
the app is not actively open. The persistent notification shows remaining
time and allows users to pause/stop the timer without opening the app.
