BRINGUP: first real LightBurn job, operator-verified

Browse Source 
Full design job (rapid / M4 cut trace / return rapid) ran smoothly end
to end on grblHAL-glowforge over TCP:23, laser locked. Records the two
driver fixes the first attempts surfaced: locked laser spindle and
continuation-wakeup cursor alignment.

**First real LightBurn job: 2026-08-02, operator-verified.** Device
setup per `LIGHTBURN.md` (GRBL over TCP:23); a full design job — rapid
in, M4 dynamic-power cut trace at commanded speed, return rapid — ran
smoothly end to end on grblHAL-glowforge (laser locked, motion only).
Two driver fixes came out of the first attempts: the locked laser
spindle (M4/$32 support without fire capability) and the
continuation-wakeup cursor alignment (back-to-back cycles previously
clamped into step bursts — jerky, step-losing rapids; found via the
per-run `clamped` stat from the operator's own job log).
**Milestone 2 (motion quality): bench-verified 2026-08-02.** The factory
motion constants were extracted from the `_RESOURCES` pulse files
(`scripts/bench/puls_profile.py`) and applied end-to-end:
