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.
