Fix breadd skel config schema; remove temp live diagnostic

- breadd.toml: the shipped skel used a stale [adapters] schema
  (keyboard/mouse/touchpad/gamepad booleans); breadd 0.6.4 expects
  hyprland/udev/power/network/bluetooth structs. `bluetooth = true` collided
  with the real AdapterToggle field and aborted the daemon at startup.
- Drop the temporary bos-live-diag serial diagnostic now that the live-session
  failures are diagnosed.
