 ### Acceptance Criteria
 
--   [ ] When adding a new anime, it is immediately saved to the database
--   [ ] When adding a new anime, only that anime is scanned for missing episodes (not full library)
--   [ ] Folder is created using the sanitized display name (e.g., "Attack on Titan" not "attack-on-titan")
--   [ ] Special characters in anime names are properly handled (`:`, `?`, etc.)
--   [ ] Existing anime entries continue to work (backward compatibility)
--   [ ] API response includes the created folder path and missing episodes count
--   [ ] Unit tests cover the new functionality
--   [ ] No regressions in existing tests
