structlog fails with BrokenPipeError when stdout is redirected (e.g., background
processes, Docker logs). Replace all structlog.get_logger() calls with
logging.getLogger() and convert keyword-style log calls to %-format strings.
Also removes stale Docs/tasks.md (2028 lines) and updates Robot Framework
tests to match current API behavior.
The TMDBClient was being instantiated but never closed, causing 'Unclosed
client session' errors in the logs. Fixed by using 'async with' context
manager which properly calls close() on exit.
Changes:
- _lookup_tmdb_id_by_name: wrapped client in async with
- _fetch_tmdb_data: wrapped client in async with
- Call _load_series_into_memory() before NFO scan phases to sync DB
to SeriesApp memory, fixing missing NFO for recently resolved folders
- Add TMDB lookup for series without cached tmdb_id during NFO creation
- Add get_tmdb_client() factory and get_tmdb_image_base_url() helpers
- Fix: use get_tv_show_details instead of deprecated get_series_details
- Fix tests: mock _load_series_into_memory in NFO scan tests
- Add nfo_scan_after_rescan config option (default: true)
- Implement year caching in AniworldLoader and EnhancedAniWorldLoader
- Make get_year abstract method in base provider
- Run NFO validation/creation after scheduled rescan completes
- Add _YearDict cache to avoid re-extracting year from HTML
