Preserve notation + grammar feature work (verified complete + green)
The parallel agent's full session, committed now that it's solo:
- Grammar: flam/drag/roll ornaments (f/F d/D z/Z, per-lane orns channel) across
src/engine.js, pico-cp/pico-explorer/pico-scroll app.py, pico/main.py, rust/track-format,
+ golden vectors / conformance (tests/, rust/track-format/tests).
- Live-sync deep-sync: SysEx 0x44 SLSYNC + 0x45 LOGSYNC (docs/livesync-protocol.md, src/livesync.js).
- PM_E-2 notation: web engine (pm_e-2.html, build/deploy/index/embed wiring) + Rust device port
(pm-ui draw_notation rewrite + LaneView.groups, pm-kit ViewMode, uisim notesim).
Verified: node tests/run.mjs 47 pass / 1 known; ./rust/run.sh green; pm-kit firmware + uisim compile.
