Merge branch 'NOOK-881' — the landing page, FAQ and downloads list said macOS 14, but the app cannot start below 14.2: a CoreAudio overlay symbol its mixer uses only exists from 14.2, and the old bundle floor let LaunchServices launch it on machines that could never run it. The FAQ now names the audio tap API rather than the observation framework, and the downloads list's 14.6+ becomes 14.2+. InputHalo and Gaze keep their own floors.

The landing page, the FAQ and the downloads list still promised macOS 14. The
app cannot start there: dyld refuses it on 14.0 and 14.1 because a
CoreAudio overlay symbol its mixer uses only exists from 14.2, and the old
floor in its bundle had LaunchServices launching it on machines that could
never run it (NOOK-881).

The FAQ answer named the observation framework as the reason for 14; the
binding reason is the per-app audio tap API, which Apple shipped in 14.2. The
downloads list said 14.6+, which was already stricter than the truth.

InputHalo and Gaze still read 14.6+; their floors are their own and this
change leaves them alone.

Tests: bun test src/routes/nook (2 pass); bunx tsc --noEmit reports nothing in
the three files changed (the checkout's 286 pre-existing errors are elsewhere).
