A show that has published for years is unbounded: GEOlino Spezial alone is 358
episodes and 5.8 GB, and the device it syncs onto is a 30 GB SD card that also
holds the rest of the library. Nothing stopped the 6-hourly poll from eventually
filling it.
Cap each show's folder at general.podcast_episode_limit (default 50, null to
keep everything), pruning the oldest past that after each sync pass.
The same limit caps what is downloaded, and it has to be one number for both.
Prune to the newest N but keep fetching everything the feed offers, and every
poll would re-download exactly the episodes the previous one deleted - forever,
at full size, since missing_episodes() decides purely from what is on disk.
There is a test for that specific loop.
Pruning only touches files named the way this module names them
(YYYYMMDD - Title.ext), so feed.txt, folder.jpg, the failed-download record and
anything placed by hand are all left alone; a parse that fails means "not ours",
not "delete it". An episode's sidecar cover goes with it. A pass that only
deleted still reports a change, because the library needs the rescan just as
much as it does after a download.

_extract_audio wrote transcoded audio to a .tmp temp path, so ffmpeg
couldn't guess a muxer from the filename and aborted on every video
episode whose source was still reachable. Pass -f mp3 explicitly instead
of relying on the extension.
Separately, a permanently 404'd episode was retried on every startup and
every 6-hour poll forever, since nothing remembered past failures. Track
failed downloads per show folder with a 7-day backoff before retrying.

- podcast_feeds.py: fetch per-episode cover art from a feed's itunes:image
(when it's genuinely distinct from the channel image) or, failing that,
from the og:image on the episode's own linked page; extract audio from
video-only enclosures via ffmpeg; match podcast-dl's filename convention
(illegal characters become "_" instead of being dropped) so enabling
feed.txt on an already-downloaded show doesn't re-download its back catalog
- scanner.py: _cover_for_episode now checks for a same-stem sidecar cover
image before falling back to embedded ID3 art and the shared folder cover
- scanner.py/__init__.py: fixed a bug where an album folder nested one level
deeper than usual (an age-range grouping folder, say) was mistaken for an
empty album and skipped; added periodic progress logging for long scans
and analysis passes

A show folder under Kinderpodcasts/ opts in by containing a feed.txt marker
naming its RSS feed. A new PodcastFeedService polls every such feed every 6
hours (and once at startup), downloads any episode not already on disk using
the existing YYYYMMDD - Title.ext convention, and triggers the same
rescan-and-broadcast sequence "Bibliothek neu einlesen" already uses - now
shared via App.rescan_library() instead of duplicated. A show with no
feed.txt is untouched, so there is no new config section for this.
