feat(web)!: implement Web Service Worker with IndexedDB and periodic sync
- Add complete Service Worker implementation with IndexedDB storage - Implement background sync for content fetch and notification delivery - Add Service Worker Manager for registration and communication - Include push notification support with VAPID key handling - Implement TTL-at-fire logic with IndexedDB persistence - Add callback management with HTTP and local callback support - Include comprehensive error handling and fallback mechanisms - Support for periodic sync and background task scheduling - Mirror Android SQLite and iOS Core Data schema in IndexedDB BREAKING CHANGE: Web implementation requires Service Worker support and HTTPS
