mboehmlaender	3dd043689e	fix: always generate CAA cover art URL, handle missing covers with onError Per CAA API docs, front-250 URLs are predictable from mbId. Remove the cover-art-archive.front check (unreliable in search results) and always construct the URL. A CoverThumb component handles 404s gracefully.

mboehmlaender	882dad57e2	fix: CD metadata dialog search/images/Weiter button - Remove auto MusicBrainz search from analyzeCd; user triggers search manually - Dialog uses single results state (replaced per search, not appended) - Add cover-art-archive to MB search includes so cover images load - Weiter button only blocked by track selection when tracks actually exist Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-12 08:32:23 +00:00
mboehmlaender	15f1a49378	fix: add cdparanoia fallback for audio CD detection in VMs udevadm media flags are not propagated in VM/passthrough scenarios.

mboehmlaender	871e39bba2	fix: reset hard before branch switch to discard stale local changes Partial writes from a failed install leave files as "local changes", blocking the checkout.
