v3.8.0

"Human Proof", the machine part (LOG #92): everything the field passes need is ready, and what a browser can check
is checked in Safari's engine too. The seven passes themselves are people's and devices' (D12, docs/en/FIELD.md):
0 of 7 done for this release.

Added

• The reference chapter's two-score scenario (a plan on the phrase, the bridge, a save restored before the landing, a
  stop while a transition waits, the decoded peak under transitionPeakMB) runs in WebKit as well as Chromium, in CI
  (npm run e2e:music -- --only=reference --browser=webkit).
• docs/{en,fr}/FIELD.md: the seven field passes (screen reader, Safari offline, a real phone, playtesters, recorded
  voices, listening, signed tag), how to make each and what to bring back; the passes template has the listening row.
• Near misses in playtests: a tap on nothing within 24 px of a target counts for that room and target; the shared
  session carries the counts (ids only) and npm run playtests lists them.
• ?fps: a frame counter (now and the lowest second) for the real-phone pass.
