Add industrial metal soundtrack with seamless loop
- assets/audio/music/zombie_industrial_loop.ogg: 57.60 s Ogg Vorbis loop generated locally with YuE2-3B on the Tesla V100 (score written for this track; vocals removed with HTDemucs). The loop is spliced at the track's structural repeat with a 0.6 s crossfade: measured seam dip <= 1.6 dB. - scripts/main.gd: "Music" AudioStreamPlayer at -11 dB, started at boot on desktop and on the start click on Web (browser autoplay policy). It forces stream.loop at runtime because the Web staging step re-imports the OGG with loop=false. - tools/test_music.gd: soundtrack test (loop, length, volume, playback, still playing after player death). - docs/MUSIC.md: source, loop construction, verification, licence. - docs/WEB-DEPLOY.md: release ab6054111f5919a8 notes. Initial commit of the project.
