Replace c2s/s2c/s2s taxonomy with IRC-native structure:
- schema/commands/ — IRC command schemas (PRIVMSG, NOTICE, JOIN, PART,
QUIT, NICK, TOPIC, MODE, KICK, PING, PONG)
- schema/numerics/ — IRC numeric reply codes (001-004, 322-323, 332,
353, 366, 372-376, 401, 403, 433, 442, 482)
- schema/message.json — base envelope mapping IRC wire format to JSON
Messages use 'command' field with IRC command names or 3-digit numeric
codes. 'body' is a string (IRC trailing parameter), not object/array.
'from'/'to' map to IRC prefix and first parameter.
Federation uses the same IRC commands (no custom RELAY/LINK/SYNC).
Update README message format, command tables, and examples to match.
C2S (7): send, join, part, nick, topic, mode, ping
S2C (12): message, dm, notice, join, part, quit, nick, topic, mode, system, error, pong
S2S (6): relay, link, unlink, sync, ping, pong
Each message type has its own schema file under schema/{c2s,s2c,s2s}/.
schema/README.md provides an index of all types with descriptions.
