twislaandClaude Opus 5.5 311eb38723 M1 step 4a: IRC protocol core (host-tested)
lib/irc: IrcMessage parse/serialize, base64, ReconnectPolicy
(5 s .. 5 min), IrcConfig (validated, persisted) and IrcSession:
registration with SASL PLAIN or NickServ, nick fallback, PING, Buffers
capped at 50 lines with unread counts, Mentions, CTCP ACTION/VERSION,
topics, /names on request only, others' join/part/quit hidden, user
commands, and rejoining after a pause. No networking: the session
returns lines to send, Log entries and Notifications.
