Wire the Max for Live device to the keyboard

Browse Source 
Step 3 of the brief: the device now holds a ScaleLighting and pushes every
scale Live reports to the Apex 7, instead of only printing it.

The controller is created lazily and injected (start(max, { createLights })),
so the device stays testable with no Max and no hardware. Around the call:
lighting work is serialized on one queue so a burst of LOM changes cannot
interleave two POSTs, an unchanged scale is never re-sent, and a GameSense
that is missing or restarted is printed once rather than on every scale
change — the scale keeps being tracked so a later retry lands on the right one.

New messages: lights 0|1, retry, address <host:port>, shutdown. The patcher
gets boxes for them plus closebang -> shutdown, and the launcher blanks the
board on SIGTERM/SIGINT, so deleting the device hands lighting back to GG.

The test runner now supports async tests, since the lighting half is async.
