clang-format had no config here, so adopting the submodule's puts both repos

Bluedroid cannot initialize beside the Lua runtime on this heap, so the
provider is NimBLE-Arduino. Scans keep the six strongest devices in a fixed
buffer rather than growing one. The standalone BLE app is gone: it was a
screen of toggles that belongs next to the other device settings.
