A separate firmware type layering a mesh debug bot on top of the stock
BLE companion example without modifying upstream sources. Replies to
!-prefixed commands (!ping, !rf, !path, !status, !stats, !neighbors,
!uptime, !time, !ver) from direct messages or allow-listed channels,
with rate limiting.
Runtime config rides the companion protocol's custom vars ("bot",
"bot.channels") settable via meshcore-cli or the phone app, persisted
to flash. Envs for Xiao S3 WIO, Xiao nRF52, Heltec V3, Heltec V4,
RAK4631, RAK3401 (WisMesh 1W Booster), T1000-E and Heltec T114 in
variants/bot_envs/platformio.ini.
