test: add comprehensive IRC integration test with two clients (#100)
check / check (push) Successful in 6s
Adds `integration_test.go` with four test functions that exercise all major IRC features using real TCP connections.
## Tests
**TestIntegrationTwoClients** — sequential two-client test covering:
- NICK/USER registration (001-004 welcome burst)
- JOIN with cross-client visibility
- PRIVMSG channel (both directions)
- PRIVMSG DM (both directions)
- NOTICE channel and DM
- TOPIC set/get/lock/unlock
- MODE query, +m (moderated), +v (voice), -t/+t (topic lock)
- NAMES (with both nicks listed)
- LIST
- WHO
- WHOIS (with channels)
- LUSERS
- NICK change (with relay to other client)
- Duplicate NICK (ERR_NICKNAMEINUSE)
- KICK (with relay + reason)
- KICK non-op error (ERR_CHANOPRIVSNEEDED)
- PING/PONG
- Unknown command (ERR_UNKNOWNCOMMAND)
- MOTD
- AWAY set/clear/RPL_AWAY on DM
- PASS post-registration
- PART with reason + relay
- PART non-existent channel error
- User MODE query
- Multi-channel messaging
- QUIT with relay
**TestIntegrationModeSecret** — verifies +s mode set and query.
**TestIntegrationModeModerated** — verifies +m blocks non-voiced users and +v enables sending.
**TestIntegrationThirdClientObserver** — verifies three-client channel message fanout.
`docker build --no-cache .` passes clean (formatting, linting, all tests, build).

feat: add traditional IRC wire protocol listener (closes #89) (#94)
check / check (push) Successful in 5s
## Summary
Adds a backward-compatible IRC wire protocol listener (RFC 1459/2812) that allows standard IRC clients (irssi, weechat, hexchat, etc.) to connect directly via TCP.
## Changes
### New package: `internal/ircserver/`
- **`parser.go`** — IRC wire protocol message parser and formatter
- **`server.go`** — TCP listener with Fx lifecycle integration
- **`conn.go`** — Per-connection handler with registration flow, PING/PONG, welcome burst
- **`commands.go`** — All IRC command handlers (JOIN, PART, PRIVMSG, MODE, TOPIC, KICK, WHOIS, etc.)
- **`relay.go`** — Message relay goroutine that delivers queued messages to IRC clients in wire format
### Modified files
- **`internal/config/config.go`** — Added `IRC_LISTEN_ADDR` environment variable
- **`internal/handlers/handlers.go`** — Broker is now injected via Fx (shared with IRC server)
- **`cmd/neoircd/main.go`** — Registered `broker.New`, `ircserver.New` as Fx providers
- **`pkg/irc/commands.go`** — Added `CmdUser` and `CmdInvite` constants
- **`README.md`** — Added IRC Protocol Listener documentation section
### Tests
- Parser unit tests (table-driven, round-trip verification)
- Integration tests: registration, PING/PONG, JOIN, PART, PRIVMSG (channel + DM), NICK change, duplicate nick rejection, LIST, WHOIS, QUIT, TOPIC, MODE, WHO, LUSERS, MOTD, AWAY, PASS, CAP negotiation, unknown commands, pre-registration errors
- Benchmarks for parser and formatter
## Key Design Decisions
- **Optional**: Listener is only started when `IRC_LISTEN_ADDR` is set
- **Shared infrastructure**: Same DB, broker, and session system as HTTP API
- **Full bridge**: IRC ↔ HTTP messages are interoperable
- **No schema changes**: Reuses existing tables
- **Broker as Fx dependency**: Extracted from handlers to be shared
## Supported Commands
Connection: NICK, USER, PASS, QUIT, PING/PONG, CAP
Channels: JOIN, PART, MODE, TOPIC, NAMES, LIST, KICK, INVITE
Messaging: PRIVMSG, NOTICE
Info: WHO, WHOIS, LUSERS, MOTD, AWAY, USERHOST
Operator: OPER
