khannurien 425eb86327 Add standalone GameSense scale lighting for the Apex 7 ...

Build step 1 of the Ableton scale-lighting brief: a dependency-free Node
script that drives the keyboard directly, with the scale passed on the
command line. Live and Max for Live come later.

Lighting uses one event with 14 context-color handlers — a background zone
covering every key except the 13 note keys, plus one handler per note key
addressed by USB HID code. Colors travel in the event frame, so handlers are
bound once and a scale change is a single POST, which is what the M4L step
will need.

Chose custom zones over bitmap mode: bitmap's 22x6 grid has no documented
index-to-key table per model, while HID codes are exact. Painting the whole
board with the background zone covers the same blackout caveat bitmap was
suggested for.

tools/fake-gamesense.js stands in for the GameSense server and renders the
resolved frame as ANSI colour, so the mapping is verifiable without hardware
or Windows.
