The row treatment for a dead playlist entry already existed -- muted
text, no play on click, no drag, no kebab, never "now playing" -- but it
only fired for track_id === null, the track-deleted case. A missing file
kept a live-looking row that failed on click.
The behavioural gate now covers both, and the presentation distinguishes
them, because they mean different things to the person reading the list.
A removed track is gone for good and keeps the strikethrough. A missing
file is a track we still have -- history, likes, the lot -- whose bytes
aren't on disk right now, so it gets an explicit "File missing" and a
title explaining it stays in the playlist and comes back on its own if
the file does. A strikethrough there would claim it was deleted, which
is a lie about a file the scanner may well adopt back tomorrow (#2528).
Skipping routes through playlistTrackToRef, which already returned null
for removed tracks and whose callers already filter nulls. Adding the
unavailable check there means every queue builder -- PlaylistCard,
systemRefetch, the detail page -- skips a missing file without any of
them learning what missing_since is.
Remove stays available on a dead row: the owner must still be able to
take it out of their own list.
When the whole queue proves unplayable (e.g. a tab left open across the
daily system-playlist rebuild — the exact stale-snapshot case), the player
now re-pulls the fresh snapshot and resumes instead of dead-ending on
"Try again". The seeder hands the store an opaque refetch closure so the
store stays decoupled from the playlist API and the per-artist
(songs_like_artist) identity problem: single-instance variants re-pull via
systemShuffle, per-artist mixes via getPlaylist(id), radio re-seeds from
its track. Bounded to one self-heal per exhaustion (reset on the next
successful play) so a still-broken refresh can't loop; "Try again" stays
the genuine last resort. Wired from PlaylistCard, the playlist detail page,
and playRadio. Issue #968.

reconstruction (#375)
PlaylistTrackRow.svelte and PlaylistCard.toTrackRefs both rebuilt
TrackRef from PlaylistTrack with the same field-by-field literal.
Server adding a new TrackRef field would have needed both sites
updated; now one helper owns the mapping.
