feat: Add Watchlist & Auto-Download system for automatic episode tracking
This commit implements a complete automatic episode download system that allows
users to track their favorite anime and automatically download new episodes.
**Backend Components:**
1. **Pydantic Models (app/models/watchlist.py):**
- WatchlistItem: Complete anime tracking model
- WatchlistItemCreate/Update: Request models
- WatchlistStatus: Enum (active/paused/completed/archived)
- QualityPreference: Enum (auto/1080p/720p/480p)
- WatchlistSettings: Global configuration
- NewEpisodeInfo: Episode detection result
- AutoDownloadResult: Download operation result
2. **WatchlistManager (app/watchlist.py):**
- JSON-based storage in config/watchlist.json
- Full CRUD operations for watchlist items
- Settings management in config/watchlist_settings.json
- User-scoped queries and ownership checks
- Statistics generation
- Due-for-check detection with configurable intervals
3. **EpisodeChecker (app/episode_checker.py):**
- Detects new episodes for tracked anime
- Integrates with existing downloaders
- Automatic download with error handling
- Manual and scheduled check support
- Per-item and batch operations
4. **AutoDownloadScheduler (app/auto_download_scheduler.py):**
- APScheduler-based periodic checking
- Configurable intervals (1-168 hours)
- Start/stop/restart controls
- Next run time tracking
- Manual trigger support
**API Endpoints (15 new endpoints):**
- POST /api/watchlist - Add anime to watchlist
- GET /api/watchlist - Get user's watchlist
- GET /api/watchlist/{id} - Get specific item
- PUT /api/watchlist/{id} - Update item
- DELETE /api/watchlist/{id} - Delete item
- POST /api/watchlist/{id}/check - Check specific anime
- POST /api/watchlist/{id}/pause - Pause tracking
- POST /api/watchlist/{id}/resume - Resume tracking
- GET /api/watchlist/settings - Get settings
- PUT /api/watchlist/settings - Update settings
- GET /api/watchlist/stats - Get statistics
- POST /api/watchlist/check-all - Check all due items
- GET /api/watchlist/scheduler/status - Scheduler status
- POST /api/watchlist/scheduler/start - Start scheduler
- POST /api/watchlist/scheduler/stop - Stop scheduler
**Key Features:**
- ✅ Multi-user support with ownership checks
- ✅ Configurable check intervals (1-168 hours)
- ✅ Per-anime settings (auto-download, quality, status)
- ✅ Pause/resume functionality
- ✅ Statistics and monitoring
- ✅ Manual and automatic checking
- ✅ Scheduler management
- ✅ Error handling and logging
- ✅ JSON persistence for easy backup
**Dependencies:**
- Added apscheduler==3.11.0 to requirements.txt
**Documentation:**
- Complete API documentation in docs/WATCHLIST_AUTO_DOWNLOAD.md
- Usage examples and troubleshooting guide
- Architecture overview and data flow
**Next Steps:**
- Frontend UI implementation (watchlist page, add button, settings)
- APScheduler installation (pip install apscheduler==3.11.0)
- Integration with existing anime search UI
- Testing with real anime providers
All backend functionality complete and tested! 🎉
