feat: Implement SQLAlchemy database layer with comprehensive models
Implemented a complete database layer for persistent storage of anime series,
episodes, download queue, and user sessions using SQLAlchemy ORM.
Features:
- 4 SQLAlchemy models: AnimeSeries, Episode, DownloadQueueItem, UserSession
- Automatic timestamp tracking via TimestampMixin
- Foreign key relationships with cascade deletes
- Async and sync database session support
- FastAPI dependency injection integration
- SQLite optimizations (WAL mode, foreign keys)
- Enum types for status and priority fields
Models:
- AnimeSeries: Series metadata with one-to-many relationships
- Episode: Individual episodes linked to series
- DownloadQueueItem: Queue persistence with progress tracking
- UserSession: JWT session storage with expiry and revocation
Database Management:
- Async engine creation with aiosqlite
- Session factory with proper lifecycle
- Connection pooling configuration
- Automatic table creation on initialization
Testing:
- 19 comprehensive unit tests (all passing)
- In-memory SQLite for test isolation
- Relationship and constraint validation
- Query operation testing
Documentation:
- Comprehensive database section in infrastructure.md
- Database package README with examples
- Implementation summary document
- Usage guides and troubleshooting
Dependencies:
- Added: sqlalchemy>=2.0.35 (Python 3.13 compatible)
- Added: alembic==1.13.0 (for future migrations)
- Added: aiosqlite>=0.19.0 (async SQLite driver)

feat: implement download queue service with persistence, priority, and retry logic
- Added comprehensive download queue service (download_service.py)
- Priority-based queue management (HIGH, NORMAL, LOW)
- Concurrent download processing with configurable limits
- Automatic queue persistence to JSON file
- Retry logic for failed downloads with max retry limits
- Real-time progress tracking and WebSocket broadcasting
- Queue operations: add, remove, reorder, pause, resume
- Statistics tracking: download speeds, sizes, ETA calculations
- Created comprehensive unit tests (test_download_service.py)
- 23 tests covering all service functionality
- Tests for queue management, persistence, retry logic
- Broadcast callbacks, error handling, and lifecycle
- Added structlog dependency for structured logging
- Updated infrastructure.md with download service documentation
- Removed completed task from instructions.md
All tests passing (23/23)
