pyr0ball 451b7ee341 feat: hardware BOM + fix critical daemon bugs (gaze dead code, FIST mapping)

- Add hardware/ directory structure (cad, cam, parts, sim, docs)
- Add hardware/bom/merlin-bci-rev0.csv — ADS1299 + ESP32-WROOM-32E full BOM
  with passive values for 8-ch EEG front-end, isolated ±5V supply, WiFi streaming
- Fix: wire gaze_est.estimate(face) into camera loop (was instantiated but never called)
- Fix: add fist, gaze_left/right/up/down to DEFAULT_MAPPINGS
- Add: ActionExecutor.backend property (replace _backend direct access in /status)
- Add: scroll_left/right, key_ctrl_z/c/v to xdotool + pyautogui backends
