Split playback into a shuffled context and a manual up-next list.
`up_next_entries` holds the same reference-plus-range rows as the
context but is never shuffled; `playback_cursor.upNextAnchor` pins the
block between a context track and its successor. `QueueRepository`
resolves a combined position by mapping through the context order and
splicing the block after the anchor, so the controller's window and
next/previous keep working.
PlaybackController gains addToQueue/playNext, consumes a queued track
when playback advances out of it, resumes the context when the block
empties, and clears the block on a new context. The queue view gets an
editable "Up next" section and a read-only context section, and the
context menu gains Play next / Add to queue for songs, albums and
playlists.
- ArtworkSeedStore now carries the flag; artwork_seeds gains a nullable nameBusy column
(DB v12, migration 11->12) so it survives cold starts with no decode
- resolve() computes the flag from the same bitmap it extracts the colour seed from, so
there is no second decode, and persists it alongside the seed
- overlaidNameBusy reuses the seed job and reads the cached flag synchronously, so the
scrim is known before the art shows; drop the fade
- bottomBandBusy now uses perceptual (gamma-space) luma, edge density and a bright
fraction, which catches busy art on dark backgrounds (issue #40) that mean/variance missed
Navidrome and gonic expose OpenSubsonic discTitles on the album response.
Parse them into a transient Album.discTitles map and persist each album's
titles in a child discs table (sourceId, albumId, disc, title) cascading
from albums. Songs keep only their disc number, and the album screen joins
by disc to render a title when one exists, falling back to "Disc N".
Titles are read opportunistically: a server that doesn't send discTitles
just leaves the table empty, so no API version negotiation is needed.
Titles apply to single- and multi-disc albums, are pruned when removed,
and are stored per album.
Schema 10 -> 11.
