Close the Recently Played Tracks tech debt: a JSON-backed play-history
store at the shared QBZ data path, surfaced as a slim-card section on
Discover Home (it hides while empty).
- recently.rs: load() reads the store newest-first; record() prepends a
track, dedupes by id and caps the list — the playback session calls
record() when a track starts
- home.rs threads a `recent` list into HomeData; HomeView renders a
"Recently Played" GridSection; artwork pipeline gains an
ArtworkTarget::Recent
The data path is complete end to end; only record() awaits the
playback session.
