FORBID ADD/DEL/LIST bans a NICK, CHAN, or EMAIL glob from being registered — a network-wide policy that gossips like an AKILL and every node enforces. Nick registration is blocked in pre_register_check (both NickServ REGISTER and the account-registration relay), and channel registration in ChanServ REGISTER. New Forbid store + events, mirroring the akill subsystem.
