First commit of the repo. Contents beyond the v0.1 simulator and layout: - Full Pico 2 W firmware (firmware/app, drivers, engine port, host test). - BANK page and 404 mode A/B removed; learned pads play exactly what was learned. - 404/MiniFreak renamed to KIT/SYNTH throughout (jacks, code, sim, docs, layout labels; wiring rebuilt). - ROLL returns to page select after a re-roll; a freshly learned track turns on. - LCD contrast 66. - ROOT and SCALE pages: 21 scales, AUTO = the seed picks; global and sticky. Intended music change: the scale table grew from 8 to 21 and AUTO picks from all of them, so every seed's scale changed. Vectors regenerated with npm run vectors, plus new key-override cases. Flash record is now version 2. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
