MusicD Remote v1.8.67

Asked for by a user: "is there any way for Smart Picks to be added to Listen
Later rather than the library (or have this as an option)?" Roon's own Listen
later cannot be reached from an extension, so this is the extension's own,
ported from Mandarin (which grew out of this extension and has had one since
its v0.5.28).

Added — Listen later

• A list of albums put aside to play another time, kept on the server by
  album identity (never by offset), so it survives a rescan and every device
  sees the same list. New table listen_later; GET/POST /api/listen-later
  (on is the state asked for, not a toggle, so two devices tapping at once both
  end where they meant to); a later live revision, so the row and the screen
  follow changes made on another device.
• Put an album aside from its ⋯ menu in the album view ("Listen later" /
  "Remove from Listen later"), from a multi-selection on any album wall, or from
  a Smart Pick's new "＋ Listen later" button.
• A Home row, newest first and hidden while the list is empty, with a switch
  and a place in the order under Settings → Home Screen like every other row.
  Existing installs get it at the end of their stored order, switched on. The
  shelf shows at most 30; the header opens the whole list.
• A Listen later screen (the row's header, or the side menu). An album Roon
  has offers Play; a Smart Pick Roon does not have yet offers Add to library
  (the same one-way favourite the Smart Picks screen uses) and Open in
  Qobuz/TIDAL, so it can be heard before deciding. Every entry has Remove.
• Leaves by itself once played through: every track of the album completed,
  on any zone and from any app, after it was put aside — Mandarin's rule. "Every
  track" comes from the track list the extension recorded when the album was
  opened; an album it has never opened stays until it is removed by hand rather
  than leaving on a guess.

Changed — where Smart Picks go

• Settings → Smart Picks: the "Add picks automatically" switch is now Send
  each day's picks to: Library / Listen later / Nowhere — ask me. Listen later
  puts the day's picks on the list WITHOUT favouriting them, so the streaming
  library stays as the user built it. Upgrading changes nothing: the old switch
  on reads as Library, off as Nowhere. The old value is still written beside the
  new one, so a downgrade keeps the choice where it can be expressed.
• "Not for me" also takes that artist's Smart Pick entries off Listen later
  (albums put aside from the album view stay); "Rebuild today's picks" with
  picks going to Listen later takes the discarded set's entries with it, rather
  than stacking five more on top at every press.

Fixed before release (8-angle review)

• The played-through check ran a JS scan of every play since the entry was
  added, inside the zone-event handler, on every counted track; it is narrowed
  to the album in SQL now.
• An entry resolved through the tolerant album match alone could land on
  another edition sharing a stripped title ("Rumours" → "Rumours (Deluxe
  Edition)"); an exact identity match is tried first. Class of error: a
  first-match lookup over a key two records share.
• The Home row no longer waits on a streaming service's favourites, which only
  the screen shows; entries carry the same source/quality badges as every other
  row; a settings write validates every field before applying any.

Tests: test/unit/listen-later.test.js (storage against the real schema,
matching, the played-through rule, the live revision), test/dom/listen-later.test.js
(the row, the screen, the Smart Picks button, the Settings choice), and the
Smart Picks build now proves the Listen later destination favourites nothing.
