Use the database as the authoritative source for missing-episode lists so
that episodes marked is_downloaded=True are never shown as missing, even
when the in-memory state is stale.
Key changes:
- EpisodeService.get_by_series() gains only_missing flag
- AnimeService uses DB-backed episodeDict and preserves downloaded episodes
during sync, skipping them when adding/removing missing episodes
- DownloadService broadcasts series_updated after marking an episode downloaded
so the frontend reflects the change immediately
- Frontend filters out series with zero missing episodes client-side and
fixes renderSeries to respect the active filter
- Unit tests updated to assert the broadcast is sent
- Add missing year field when building series list in anime_service
- Add _create_missing_nfo to generate minimal NFO for series without one
- Update perform_nfo_repair_scan to detect and create missing NFOs
- Add semaphore-protected async creation with TMDB rate limiting

- anime_service: pass year when syncing from data files
Retry count and queue status were in-memory only and lost on
restart, so failed downloads could not be safely resumed and
permanently-failed episodes silently blocked re-queueing via the
episode-id unique index.
- Add status + retry_count columns to DownloadQueueItem
- Replace unique(episode_id) with unique(episode_id, status) so
permanently_failed rows do not block new pending entries
- Add PERMANENTLY_FAILED to DownloadStatus enum
- Persist retry_count on each failure; mark permanently_failed once
max_retries reached
- QueueRepository reads status/retry_count from DB instead of
defaulting to PENDING/0
- Stop double-incrementing retry_count in retry_failed_items;
increment only happens in _process_download on failure

Change _remove_episode_from_missing_list to set is_downloaded=True
and populate file_path via EpisodeService.mark_downloaded, instead of
deleting the Episode row. Preserves download history so queries can
distinguish series with downloaded episodes from completely unwatched
series.
- Pass serie_folder to construct file_path
- Look up series_id via AnimeSeriesService.get_by_key
- Update tests to mock mark_downloaded path
- Document episode lifecycle in docs/DEVELOPMENT.md

- Fix race condition: next_run_time only available after scheduler.start()
- Handle None gracefully in logging
- Add debug logging to _perform_rescan and _run_rescan_job
- Document scheduler troubleshooting in DEVELOPMENT.md
- New _search_with_fallback() method tries multiple strategies:
1. Primary query with year filter (de-DE locale)
2. Alternative titles with ja-JP / en-US locales
3. English search (en-US)
4. Search without year constraint
5. Punctuation-normalized query
- create_nfo() accepts new alt_titles param for Japanese/title fallback
- Better match rate for anime with non-English titles

Use regex to strip all trailing year suffixes before adding the canonical
one, preventing duplication like 'Show (2021) (2021) (2021)'.

- Ensure idempotent behavior across multiple folder rename runs
- Add 7 unit tests covering the bug cases and edge scenarios
Fixes: 86 Eighty Six (2021) (2021)..., Alma-chan (2025) (2025)...
