Lane E R13 (v3.0-beta): gigKey rename + grunge/covers beds + instrument decimation
- debt #1: the manifest music key IS the gigKey, always gig-<genreKey>. Renamed
pubrock-live -> gig-pubrock (files + gen_audio + build_manifest); old files deleted.
B/F switch readers, F deletes the GIG_BED bridge (both fail soft to silence til then).
- two new gig beds: gig-grunge (band_room, quiet-loud dynamic) + gig-covers (RSL, mellow
organ-led); procedural/seeded/loopable/$0. New organ() + grungechord() synth helpers.
- decimate the 5 instrument GLBs to 14k tris each (was 43-96k; fleet 236k->70k, -70%) via
collapse (thin features survive); _hi hi-poly originals kept for depot; thumbs re-rendered.
- manifest regen (validates 0/0 incl --depot); app boots clean flags-off / ?gigs=1 (3-venue
district, all 3 beds resolve) / ?noassets=1&gigs=1 (0 audio+GLB fetches).
- depot re-publish (14k bytes + _hi originals) gated on John's OK.
