Clickable previews: exact app deep-links everywhere

Every rendered still links to the app frame that produced it (song + seed + frame + venue/viz pins + probe warm-up, new window), via shared src/ui/preview.js. Supporting work, each measured: app honors ?frame/?venueSel/?viz/?warm= with pre-build pins (Show.applyPins) and primes deep-link loads; shared pinViz/pinVenueShell paths for gallery, filmstrip and app; probes prime and carry their warm-up; bank probes analyse the bank PCM and file decode is fixed-rate with bit-exact WAV parsing so app and probes see identical samples; materials built mid-update compile synchronously (needsCompile). Round trip verified bit-identical gallery-versus-app.
