Release 2026.08.01-1

Lyrics, versioning, and the song page's fact line.

- Lyrics are suggested at submission and never imposed: the worker makes one
  LRCLIB lookup, and Hae sanoitukset re-queries with whatever title and artist
  are typed. Neither overwrites what the submitter wrote. They live on the
  submission, travel to the song at publish, and stay editable after the song
  locks — the lock freezes what a song claims to be, and nobody reviewed the
  lyrics
- The review strip reads and writes side by side: lyrics left, review right.
  Synced LRC highlights the playing line and seeks on click; plain text scrolls
  continuously with a nudge knob. Following can be turned off
- CalVer YYYY.MM.DD-N, injected from the git tag with -ldflags, shown in the
  footer, the startup log and /healthz
- The song page's metadata became four labelled cells instead of one flat run
  of five different kinds of fact

Fixes: publishing wiped lyrics the worker had just fetched (a request that
omitted a field cleared it), lyric auto-scroll landed in the wrong place, and
the fader shifted the deck sideways at score 100.
