Remote artwork refs now check the shared disk image cache before reaching
MPRIS/notifications online too (slice 3b only did it offline): a cache hit
hands desktop widgets a file:// URL instead of making them re-download
what the app already fetched. On an online miss the remote URL passes
through and a bounded re-resolver (500ms x 20) upgrades to file:// once
the now-playing bar's own fetch lands in the cache - pushed at most once
via a new (track id, art URL) metadata dedupe that also stops identical
re-pushes on resume/seek. Offline miss semantics unchanged.
