chore: bump version

Prevent fully-downloaded series from being queued by auto-download:

- SerieList.GetMissingEpisode(): filter by is_downloaded instead of
  checking if episodeDict is non-empty. episodeDict from the DB
  relationship includes all episodes (including downloaded), so a
  series with only downloaded episodes still had a truthy episodeDict.

- AnimeSeries.episodeDict property: skip episodes where is_downloaded=True
  when building the dict from the DB relationship. This makes the
  property consistent with the is_downloaded filtering already done
  manually in list_series_with_filters(), and ensures that calling
  code anywhere in the codebase gets the correct missing-episode view.

Fixes hana-kimi (and any other fully-downloaded series) incorrectly
appearing in the auto-download queue after a rescan.

-`SeriesApp` is initialized with `skip_load=True` passed to `SerieList`, preventing automatic loading of series from data files on every instantiation. Series data is loaded once during application setup via `sync_series_from_data_files()` in the FastAPI lifespan, which reads data files and syncs them to the database. Subsequent operations load series from the database through the service layer.

-3. **Repair** — Series whose NFO is incomplete are queued for background reload

 - **Queue Organization**: Displays downloads organized by status (pending, active, completed, failed)
 - **NFO Integration**: Automatic NFO and media file creation before episode downloads
 - **Manual Start/Stop Control**: User manually starts downloads one at a time with Start/Stop buttons
-- **FIFO Queue Processing**: First-in, first-out queue order (no priority or reordering)
+- **Queue Processing Order**: Items processed in user-defined order via drag-and-drop reordering (`POST /api/queue/reorder`)
 - **Single Download Mode**: Only one download active at a time, new downloads must be manually started
 - **Download Status Display**: Real-time status updates and progress of current download
 - **Queue Operations**: Add and remove items from the pending queue
