feat(android): add complete DailyNotification plugin implementation

- Add full DailyNotificationPlugin with @CapacitorPlugin annotation
- Implement echo method for testing plugin connectivity
- Add comprehensive notification functionality with offline-first approach
- Include performance optimization and error handling classes
- Add WorkManager integration for background content fetching
- Plugin now ready for testing with Capacitor 6 registration
