Progress ring now measures completion against the episodes actually queued (episodes.length) instead of the show's full leafCount, and advances smoothly using per-episode progress. The completed show/season download button reopens the download-options dialog (with a Delete row) so users can fetch more episodes or switch to sync instead of only deleting.
The browse grid listens for DeletionEvents and decrements each show's
leafCount, evicting the show when the count hits zero. Download-only
deletions (isDownloadOnly: true) fired one event per episode, so deleting
every downloaded episode of a show drove its leafCount to zero and removed
it from browse - even though the content still exists on the server.
Browse is online-only (the Libraries tab is hidden when offline) and always
reflects server-side content, so it must ignore download-only deletions.
Add a guard at the top of onDeletionEvent, matching the existing
isDownloadOnly contract already honored by media_detail_screen.
