Restructures around one folder per game, each with its own joyful
config, launch wrapper, and (if needed) a stateful daemon for physical
switches that need game-state feedback. template/ generalizes that
pattern (bare passthrough config, template wrapper, template daemon)
for mapping new games. space-engineers/ is the first instance, built
from the original mapping brief; find_codes.py is shared across games.
All device codes/keybinds/HUD calibration are still TODO pending
hardware access.
