Supplementary repair runs over downloads whose video is already complete, so
it no longer emits a downloading transition, and artwork updates carry the
row's real status instead of asserting downloading. Previously a reconnect
left completed downloads stuck at "downloading 0%" until the next DB read.
Storage exhaustion fails every active row in one transaction, so
failActiveDownloadsForStorageFull now returns the affected keys and each one
gets a failed event; only the triggering key was announced before.
The post-recovery database open also closes its handle before rethrowing. A
failing storage-full write abandoned a drift background isolate and its
SQLite handles on every retry.
Consolidates duplicated logic behind shared implementations — paginated
grid tabs, focus chrome, cached remote stores, sheet selection columns,
the server artifact store and a test fixture layer — and removes code
that had become unreachable. Net reduction of about 5,500 lines with no
behaviour change.
Where a fix had landed separately in code that moved into a shared
helper, the fix was re-applied inside the helper rather than left behind
in the copy that went away.
Introduces shared seams for paginated views, D-pad reorder, media control
routing, async singletons and the device method channel, then points the
open-coded copies at them.
Also removes unused models and duplicated provider/server plumbing, folds
the twice-implemented artifact store in the server, and factors the
repeated Flutter toolchain prologue in CI into a composite action.
