Helpful script to prevent bots from running everywhere when testing squad disconnects:

sv_neo_preround_freeze_time 2; mp_chattime 2;
sv_neo_bot_cmdr_enable 1;
sv_neo_bot_cmdr_debug_pause_uncommanded 1;
neo_ctg_round_timelimit 99;

To test bots notifying that they are joining another player's squad, one can use bot_mimic 1 to have bots press the use key on another bot.

I think this definitely could be improved a bit. Not sure if the chat is the right place for this information (though many games do this), and I'm not confident that replacing the squad name with the commander's name is a good way to differentiate the bot joining the squad the local player is in from the bot joining some other squad.

The arma series does the same thing you're doing here, it will also highlight messages that are relevant to the local player with an inverted colour scheme to separate them from chatter that's relevant to other squad members or chatter that's relevant to the whole squad

I think this could be an interesting avenue of investigation, but probably for another PR
