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. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
