feat: Add NFO metadata infrastructure (Task 3 - partial)
- Created TMDB API client with async requests, caching, and retry logic - Implemented NFO XML generator for Kodi/XBMC format - Created image downloader for poster/logo/fanart with validation - Added NFO service to orchestrate metadata creation - Added NFO-related configuration settings - Updated requirements.txt with aiohttp, lxml, pillow - Created unit tests (need refinement due to implementation mismatch) Components created: - src/core/services/tmdb_client.py (270 lines) - src/core/services/nfo_service.py (390 lines) - src/core/utils/nfo_generator.py (180 lines) - src/core/utils/image_downloader.py (296 lines) - tests/unit/test_tmdb_client.py - tests/unit/test_nfo_generator.py - tests/unit/test_image_downloader.py Note: Tests need to be updated to match actual implementation APIs. Dependencies installed: aiohttp, lxml, pillow
