The Vue test app was missing the NotifyReceiver registration in
AndroidManifest.xml, preventing alarm broadcasts from being delivered
to the BroadcastReceiver. This caused notifications scheduled via
setAlarmClock() to fire but not display.
Added NotifyReceiver registration matching the working android-test-app
configuration. Also includes supporting improvements:
- Enhanced alarm scheduling with setAlarmClock() for Doze exemption
- Unique request codes based on trigger time to prevent PendingIntent conflicts
- Diagnostic methods (isAlarmScheduled, getNextAlarmTime, testAlarm)
- TypeScript definitions for new methods
Verified: Notification successfully fired at 09:41:00 and was displayed.
