feat: Implement Android native plugin with offline-first pipeline
- Add DailyNotificationPlugin main class with Capacitor integration - Implement NotificationContent model following project directive schema - Create DailyNotificationStorage with tiered storage approach - Add DailyNotificationScheduler with exact/inexact alarm support - Implement DailyNotificationFetcher for background content retrieval - Create DailyNotificationReceiver for alarm handling - Add WorkManager workers for background tasks and maintenance - Implement prefetch → cache → schedule → display pipeline - Add comprehensive error handling and logging - Support battery optimization and adaptive scheduling
