feat(ios): implement Phase 2.1 iOS background tasks with T–lead prefetch
- Add DailyNotificationBackgroundTaskManager with BGTaskScheduler integration - Add DailyNotificationTTLEnforcer for iOS freshness validation - Add DailyNotificationRollingWindow for iOS capacity management - Add DailyNotificationDatabase with SQLite schema and WAL mode - Add NotificationContent data structure for iOS - Update DailyNotificationPlugin with background task integration - Add phase2-1-ios-background-tasks.ts usage examples This implements the critical Phase 2.1 iOS background execution: - BGTaskScheduler integration for T–lead prefetch - Single-attempt prefetch with 12s timeout - ETag/304 caching support for efficient content updates - Background execution constraints handling - Integration with existing TTL enforcement and rolling window - iOS-specific capacity limits and notification management Files: 7 changed, 2088 insertions(+), 299 deletions(-)
