- All self-advert paths (CMD_SEND_SELF_ADVERT, CMD_EXPORT_CONTACT,
MyMesh::advert()) now use bot advert name with [MCBOT] suffix when
bot_prefs.enabled, via new getAdvertNodeName() helper
- Initial flood advert at 120s after boot instead of 24h, so other
nodes see [MCBOT] in the contact name shortly after the bot boots
- AUTO_ADD_OVERWRITE_OLDEST set by default on CMESH_BOT builds, so
bots don't silently stop accepting contacts when the table fills
Patches 0001-0005 re-exported (cosmetic series-count bump 1/5 -> 1/6).
