tuiplay 0.7.24

This release rolls up every change since the last published release (0.7.20):
the freetext lyrics search, the per-song lyric timing offset, and two
interface fixes.

Added

• Freetext lyrics search. While the lyrics view is open, /
  (lyrics_search) opens a search prompt. The query runs against the local
  lrclib dump (title/artist prefix match, with extra words as filters) and
  against the lrclib.net search endpoint; the results merge and dedupe. Each
  hit carries its lyrics, so picking it needs no second lookup. Enter on a
  hit shows its lyrics; while a song plays they are saved to the lyrics cache
  under that song's key, so the automatic lookup finds them from then on.
  [..] or 4 returns to the playing song's lyrics.
• lyrics_search key action (default /), rebindable in [keys].
• Lyric timing offset. While the lyrics view shows synced lyrics, ,
  (lyrics_earlier) shifts the active-line timing 0.1 s earlier and .
  (lyrics_later) shifts it 0.1 s later, clamped to ±10 s. The offset
  shows in the lyrics page title (for example [+0.3s]) and persists per
  song in a .offset sidecar file in the lyrics cache directory, so it
  comes back with the song. A zero offset removes the file.
• lyrics_earlier and lyrics_later key actions (defaults , and .),
  rebindable in [keys].

Fixed

• Toggling the navigation panel (1/2) no longer leaves a stale queue row
  stuck at the top of the pane. The panel toggle changes the queue-pane
  width, and Bubble Tea's line diff could leave the previously highlighted
  row on screen; the interface now forces a full repaint when the panel
  visibility flips.
• A track load no longer blocks the interface loop; playback starts without
  stalling the UI.
• The first-run config template glued two [keys] comment lines together
  (crossfade_set and save_playlist).
