- Create internal/irc/ package with all IRC numeric reply codes (RFC 1459/2812) and command string constants as the single source of truth - Replace all 69+ bare numeric string literals in api.go with named constants (e.g. irc.RplWelcome, irc.ErrNoSuchChannel) - Add 'code' (int) and named 'command' (e.g. RPL_YOURHOST) fields to IRC message JSON replies via irc.Name() lookup in scanMessages - Deduplicate command constants: remove local definitions from api.go, cmd/neoirc-cli/main.go, and cmd/neoirc-cli/api/client.go; all now import from internal/irc - Fix dead code: remove handleListCmd/handleWhoCmd/handleWhoisCmd/ sendWhoisNumerics that were unreachable due to dispatchCommand routing LIST/WHO/WHOIS to dispatchInfoCommand before dispatchQueryCommand. Route these commands to dispatchQueryCommand which has the improved implementations (e.g. ListAllChannelsWithCounts single-query vs N+1) - Update enqueueNumeric and respondIRCError signatures from string to int - Update test helper findNumeric to check the new 'code' JSON field Closes #52
