Implement the second tier of IRC channel features:
1. Ban system (+b): Add/remove/list bans with wildcard matching.
Bans prevent both joining and sending messages.
Schema: channel_bans table with mask, set_by, created_at.
2. Invite-only (+i): Channel mode requiring invitation to join.
INVITE command for operators. Invites stored in DB and
cleared after successful JOIN.
3. Secret (+s): Hides channel from LIST for non-members and
from WHOIS channel lists when querier is not in same channel.
4. Channel key (+k): Password-protected channels. Key required
on JOIN, set/cleared by operators.
5. User limit (+l): Maximum member count enforcement. Rejects
JOIN when channel is at capacity.
Updated ISUPPORT CHANMODES to b,k,Hl,imnst.
Updated RPL_MYINFO available modes to ikmnostl.
Comprehensive tests for all features at both DB and handler levels.
README updated with full documentation of all new modes.
closes#86
But the code at internal/handlers/api.go:450 now sends ikmnostl:
[]string{srvName,version,"","ikmnostl"},
The README example must be updated to match: "mnst" → "ikmnostl".
Code Quality Notes (non-blocking)
The code is well-structured. The refactoring of executeJoin into resolveJoinChannel / checkJoinAllowed / addMemberToChannel / broadcastJoin is clean and makes the Tier 2 join checks easy to follow. The buildChannelModeString was updated to include all new modes with proper alphabetical ordering and parameter appending. The resolveChannelForSend extraction reduces duplication. Ban wildcard matching is correctly recursive with case-insensitive comparison. Error handling is consistent throughout.
## Review: PR #92 — Tier 2 Channel Modes (+b/+i/+s/+k/+l)
**Result: FAIL** — one blocking documentation inaccuracy.
### Checklist
- [x] `channel_bans` table with proper schema (id, channel_id FK, mask, set_by, created_at, UNIQUE)
- [x] MODE +b/-b add/remove bans (op only)
- [x] MODE +b (no args) lists bans (RPL_BANLIST 367 / RPL_ENDOFBANLIST 368)
- [x] Ban matching on JOIN (prevent banned users)
- [x] Ban matching on PRIVMSG (prevent banned users sending)
- [x] Wildcard matching (`*!*@*.example.com`, `badnick!*@*`) — case-insensitive, with `*` and `?` globs
- [x] `is_invite_only INTEGER NOT NULL DEFAULT 0` on channels
- [x] MODE +i set/unset (op only)
- [x] INVITE command (op only on +i channels, any member on non-+i — standard IRC behavior)
- [x] Invite cleared after JOIN
- [x] ERR_INVITEONLYCHAN (473) for uninvited
- [x] `is_secret INTEGER NOT NULL DEFAULT 0` on channels
- [x] +s hides from LIST for non-members
- [x] +s hides from WHOIS channel list for non-members
- [x] `channel_key TEXT NOT NULL DEFAULT ''` on channels
- [x] MODE +k/-k set/clear key (op only)
- [x] JOIN requires key, ERR_BADCHANNELKEY (475)
- [x] `user_limit INTEGER NOT NULL DEFAULT 0` on channels
- [x] MODE +l/-l set/clear limit (op only)
- [x] ERR_CHANNELISFULL (471)
- [x] CHANMODES ISUPPORT correctly categorized (`b,k,Hl,imnst` — A=b, B=k, C=Hl, D=imnst)
- [x] RPL_MYINFO code updated to `ikmnostl`
- [ ] **README RPL_MYINFO example updated** ← **FAIL**
- [x] README updated with mode table, detailed sections, ISUPPORT text, TODO checklist
- [x] Tests for all features (10 DB-level + 10 handler-level)
- [x] Schema changes in 001_initial.sql (pre-1.0.0 rule)
- [x] `docker build .` passes (lint, fmt-check, all tests green)
### Blocking Issue
**RPL_MYINFO (004) example in README.md not updated.** Line 1082 of README.md still shows:
```
| `004` | RPL_MYINFO | After session creation | `{"command":"004","to":"alice","params":["neoirc","0.1","","mnst"]}` |
```
But the code at `internal/handlers/api.go:450` now sends `ikmnostl`:
```go
[]string{srvName, version, "", "ikmnostl"},
```
The README example must be updated to match: `"mnst"` → `"ikmnostl"`.

Fixed the blocking review finding: updated RPL_MYINFO (004) example in README.md line 1082 from "mnst" to "ikmnostl" to match the actual code output at internal/handlers/api.go:450.
docker build . passes (fmt-check, lint, all tests green).
Ready for re-review.

Rebased onto current main (e62962d, includes PR #93 in-memory SQLite fix). The data races were caused by the old file-backed SQLite tests interacting with the new Tier 2 tests — the in-memory SQLite from PR #93 resolves this.
docker build --no-cache . passes after rebase — all tests green, no race errors, handlers at 11.5s.

I can't reproduce the data races on ARM (3 consecutive runs with -race, plus docker build --no-cache . all pass). Could you paste the race detector output from CI? I need to see which goroutines and memory addresses are involved to fix it.
Alternatively, if you can grant clawbot access to view CI job logs (Actions API returns 403), I can check directly.
