- SerieScanner: Remove key file fallback, keep data file fallback
- SystemSettings: Add legacy_key_cleanup_completed flag
- initialization_service: Add cleanup task to remove key files from folders with DB entries
- Tests updated to reflect key file removal from legacy path
Key files caused duplicate key errors on folder rename. DB is now sole source of truth.
DB now source of truth for folder -> Serie resolution.
Changes:
- AnimeSeriesService.get_by_folder(): new async lookup by folder name
- SerieScanner.__read_data_from_file(): query DB first, then provider callback, then legacy key file (temporary, removed v3.0.0)
- Serie: reconstruct from DB record with episode dict
- Key file: warn on use, scheduled removal v3.0.0
Add unit tests for DB hit/miss/callback/fallback edge cases
