Me Here 604927f53a Add pm-grid: Rust firmware for the Pico Scroll Pack (RP2040) 
Rust sibling of pico-scroll/app.py — the PM_G-1 'Grid' 17x7 LED metronome on a
plain RP2040 Pico (thumbv6m, not the Pico 2). LED-first milestone:

- IS31FL3731 driver: vendored bulk 144-byte framebuffer, one I2C block write per
  frame (port of the CircuitPython Matrix; the is31fl3731 crate isn't used).
- Polymeter scheduler driven by track-format::schedule::lane_durs (the cross-impl
  contract) + per-lane step clocks + tempo ramp + gap-trainer.
- 4-button input (A play/stop·hold=view, B next-track·hold=next-setlist, X/Y tempo).
- Built-in set lists; 3 views: Ticker (default), Grid, Pendulum.
- Ticker (user-designed): name infinite-scrolls left; BPM pinned right rotated 90
  CCW = hundreds dot-bar (1 dot/100) + last 2 digits rotated. 130 -> 1 dot + '30'.
- Build scaffolding: rp2040-hal 0.10 + boot2, memory.x, build.sh + uf2.py (RP2040
  family id). thumbv6m-none-eabi added to rust/Containerfile. Excluded from the
  host workspace like pm-kit. Compiles clean -> 48 KB pm-grid.uf2.

Audio (USB-MIDI; the board has no speaker), live-sync, firmware push, practice log
and playback-flow auto-advance are deferred to the next milestone (as on pm-kit).

Also: delete COORDINATION.md (solo now); docs/rust-port.md updated with pm-grid
status + corrected Grid driver-matrix row.

Rust port — track-format crate (Stage 1)

Pure parse/serialize codec for the track DSL, validated against the shared golden vectors (tests/fixtures/track-format.json) — the third implementation alongside engine.js and app.py. See docs/rust-port.md for the staged plan.

All tooling runs in a container (per the develop-in-container rule):

./rust/run.sh            # cargo test — runs the conformance + idempotency suite
./rust/run.sh cargo build
./rust/run.sh bash       # interactive shell in the crate
