Services IJOIN was ':<uid> IJOIN <chan>' with no membership id, but InspIRCd
requires <chan> <membid> (min 2 params). On link the ircd rejected the whole
server connection with 'Insufficient parameters' the moment a BotServ bot joined
its assigned channel, splitting services. Add a monotonic membid, matching how
InspIRCd itself sends IJOIN. Validated against a real InspIRCd 4 with production
data: full burst to ENDBURST, all bot IJOINs accepted, no split.
Adds channel moderation commands sourced from the ChanServ pseudoclient.
Tracks connected users' nicks and hosts so targets can be resolved by
nick and banned by *!*@host. All commands require operator access.
Accounts are an append-only JSONL event log (state is the fold of the log) with
argon2id-hashed passwords. NickServ gains REGISTER <password> [email] and
IDENTIFY <password>; the engine tracks UID->nick from the burst so a command
resolves to the sender's current nick. Classic and ircd-agnostic — the cap-based
account-registration forward is the next step.
Protocol-agnostic core: a Protocol trait maps raw server-to-server lines to a
normalized event/action model, so the engine never touches a raw line and a new
ircd is one new module. Adds event-log state (state is a fold over the log) and
a service framework. First protocol impl links to an InspIRCd (insp4) uplink —
completes the CAPAB/SERVER handshake, bursts, and introduces NickServ.
