reconcile: commit uncommitted live /srv state (playback fix + prefetch, SF favicon, smooth scroll, scripts)

The live working tree /srv/prutfolio was ahead of the bare repo with direct
server edits that had never been committed back. The deploy hook does
checkout -f main, so the next deploy would have reverted the 3 modified
tracked files to f33db01 and lost this work:

• audio-player.js: robust playback — retry+backoff on network hiccups (no longer skipping immediately) + next-track prefetch (downloads the next track while the current one plays -> ended->next swaps instantly, covering the autoplay lapse). Fix for the sometimes-next-doesn't-play bug.

• server.js: favicon mark p -> SF (SoundFabrics rebrand). shell.ejs: audio-player.js cache buster ?v=5 -> ?v=6 + favicon ?v=sf.

• Plus previously untracked project files committed: lenis.min.js + smooth-scroll.js (not yet wired), scripts/ (v9 import/migration), deploy/ docs (DEPLOY.md/backup.sh/nginx/verify.ps1), .well-known/assetlinks.json. audio-player.js.bak.20260614 deliberately NOT committed.
