- Add DailyNotificationDatabase.java with three-table schema and WAL configuration - Add DailyNotificationMigration.java for SharedPreferences to SQLite migration - Add DailyNotificationDatabaseTest.java with comprehensive unit tests - Add ConfigureOptions interface with dbPath, storage mode, and TTL settings - Add configure() method to DailyNotificationPlugin interface - Update Android plugin with SQLite integration and automatic migration - Update web implementations to implement new configure() method - Add phase1-sqlite-usage.ts example demonstrating shared storage configuration This implements the critical Phase 1.1 gate for shared SQLite storage: - App and plugin can open the same SQLite file with WAL mode - Automatic migration from SharedPreferences preserves existing data - Schema version checking prevents compatibility issues - Concurrent reads during background writes enabled - Configuration API supports both shared and tiered storage modes Files: 8 changed, 1204 insertions(+)research/notification-plugin-enhancement
