## Summary
Fixes IRC client SPA issues reported in [issue #57](#57).
## Changes
### Server-side
- **Default MOTD**: Added figlet-style ASCII art MOTD for "neoirc" as the default when no MOTD is configured via environment/config
- **MOTD command handler**: Added `MOTD` case to `dispatchCommand` so clients can re-request the MOTD at any time (proper IRC behavior)
### SPA (web client)
- **`/motd` command**: Sends MOTD request to server, displays 375/372/376 numerics in server window
- **`/query nick [message]`**: Opens a DM tab with the specified user, optionally sends a message
- **`/clear`**: Clears messages in the current tab
- **Firefox `/` key fix**: Added global `keydown` listener that captures `/` when input is not focused, preventing Firefox quick search and redirecting focus to the input element. Also auto-focuses input on SPA init.
- **MOTD on resumed sessions**: When restoring from a saved token, the MOTD is re-requested so it always appears in the server window
- **Updated `/help`**: Shows all new commands with descriptions
- **Login screen MOTD styling**: Improved for ASCII art display (monospace, proper line height)
## Testing
- `docker build .` passes (includes `make check` with tests, lint, fmt-check)
- All existing tests pass with no modifications

## Changes
- Change `Appname` from `"chat"` to `"neoirc"` in `cmd/chatd/main.go`
- Change default `DBURL` from `file:./data.db?_journal_mode=WAL` to `file:///var/lib/neoirc/state.db?_journal_mode=WAL` in both `internal/config/config.go` and the `internal/db/db.go` fallback
- Create `/var/lib/neoirc/` directory in Dockerfile with proper ownership for the `chat` user
- Update README.md to reflect new defaults (DBURL table, `.env` example, docker run example, SQLite backup/location docs)
- Remove stale `data.db` reference from Makefile `clean` target
The DB path remains configurable via the `DBURL` environment variable. No Go packages were renamed.

- Document POST /api/v1/logout endpoint
- Document GET /api/v1/users/me endpoint
- Add 'users' field to GET /api/v1/server response docs
- Fix config: SESSION_TIMEOUT -> SESSION_IDLE_TIMEOUT
- Update storage section: session expiry is implemented
- Update roadmap: move session expiry to implemented
- Remove dead SessionTimeout config field from Go code
The background idle cleanup (DeleteStaleUsers) was removing stale
clients/sessions directly via SQL without sending QUIT notifications
to channel members. This caused timed-out users to silently disappear
from channels.
Now runCleanup identifies sessions that will be orphaned by the stale
client deletion and calls cleanupUser for each one first, ensuring
QUIT messages are sent to all channel members — matching the explicit
logout behavior.
Also refactored cleanupUser to accept context.Context instead of
*http.Request so it can be called from both HTTP handlers and the
background cleanup goroutine.
- Use context.Background() for cleanup goroutine instead of
OnStart ctx which is cancelled after startup completes
- Rename GetSessionCount→GetUserCount, DeleteStaleSessions→
DeleteStaleUsers to reflect that sessions represent users
- HandleLogout now fully cleans up when last client disconnects:
parts all channels (notifying members via QUIT), removes
empty channels, and deletes the session/user record
- docker build passes, all tests green, 0 lint issues
- Periodic cleanup loop deletes stale clients based on SESSION_IDLE_TIMEOUT
- Orphaned sessions (no clients) are cleaned up automatically
- last_seen already updated on each authenticated request via GetSessionByToken
- POST /api/v1/logout: deletes client token, returns {status: ok}
- GET /api/v1/users/me: returns session info (delegates to HandleState)
- Add DeleteClient, GetSessionCount, ClientCountForSession, DeleteStaleSessions to db layer
- Add user count to GET /api/v1/server response
- Extract setupAPIv1 to fix funlen lint issue
Backend:
- Session/client UUID model: sessions table (uuid, nick, signing_key),
clients table (uuid, session_id, token) with per-client message queues
- MOTD delivery as IRC numeric messages (375/372/376) on connect
- EnqueueToSession fans out to all clients of a session
- EnqueueToClient for targeted delivery (MOTD)
- All queries updated for session/client model
SPA client:
- Long-poll loop (15s timeout) instead of setInterval
- IRC message envelope parsing (command/from/to/body)
- Display JOIN/PART/NICK/TOPIC/QUIT system messages
- Nick change via /nick command
- Topic display in header bar
- Unread count badges on inactive tabs
- Auto-rejoin channels on reconnect (localStorage)
- Connection status indicator
- Message deduplication by UUID
- Channel history loaded on join
- /topic command support
Closes#9
Security:
- Add channel membership check before PRIVMSG (prevents non-members from sending)
- Add membership check on history endpoint (channels require membership, DMs scoped to own nick)
- Enforce MaxBytesReader on all POST request bodies
- Fix rand.Read error being silently ignored in token generation
Data integrity:
- Fix TOCTOU race in GetOrCreateChannel using INSERT OR IGNORE + SELECT
Build:
- Add CGO_ENABLED=0 to golangci-lint install in Dockerfile (fixes alpine build)
Linting:
- Strict .golangci.yml: only wsl disabled (deprecated in v2)

- Fix parallel test safety (viper global state prevents parallelism)
- Use t.Context() instead of context.Background() in tests
Docker build verified passing locally.

- Remove unused //nolint:gosec directives
- Replace context.Background() with t.Context() in tests
- Use goimports formatting for all files

- Integration tests for all API endpoints (session, state, channels, messages)
- Tests for all commands: PRIVMSG, JOIN, PART, NICK, TOPIC, QUIT, PING
- Edge cases: duplicate nick, empty/invalid inputs, malformed JSON, bad auth
- Long-poll tests: delivery on notify and timeout behavior

Major changes:
- Consolidated schema into single migration with IRC envelope format
- Messages table stores command/from/to/body(JSON)/meta(JSON) per spec
- Per-client delivery queues (client_queues table) with fan-out
- In-memory broker for long-poll notifications (no busy polling)
- GET /messages supports ?after=<queue_id>&timeout=15 long-polling
- All commands (JOIN/PART/NICK/TOPIC/QUIT/PING) broadcast events
- Channels are ephemeral (deleted when last member leaves)
- PRIVMSG to nicks (DMs) fan out to both sender and recipient
- SPA rewritten in vanilla JS (no build step needed):
- Long-poll via recursive fetch (not setInterval)
- IRC envelope parsing with system message display
- /nick, /join, /part, /msg, /quit commands
- Unread indicators on inactive tabs
- DM tabs from user list clicks
- Removed unused models package (was for UUID-based schema)
- Removed conflicting UUID-based db methods
- Increased HTTP write timeout to 60s for long-poll support
Migration 003 created tables with INTEGER keys referencing TEXT primary
keys from migration 002, causing 'no such column' errors. Fix by
properly dropping old tables before recreating with the integer schema.
Rewrite all tests to use the queries.go API (which matches the live
schema) instead of the model-based API (which expected the old UUID
schema).
CreateUser, GetUserByNick, GetUserByToken exist in both db.go (model-based,
used by tests) and queries.go (simple, used by handlers). Rename the
model-based variants to CreateUserModel, GetUserByNickModel, and
GetUserByTokenModel to resolve the compilation error.
- Fix stuttering type names (e.g. config.ConfigParams → config.Params)
- Add doc comments to all exported types/functions/methods
- Add package doc comments to all packages
- Fix JSON tags to camelCase
- Extract magic numbers to constants
- Add blank lines per nlreturn/wsl_v5 rules

- Unexport NewLoggingResponseWriter (not used externally)
- Replace for-range on ctx.Done() with channel receive
- Rename unused parameters to _
- AGENTS.md: all changes via feature branches, no direct main commits
- internal/models/model.go: DB interface + Base struct for all models
- internal/models/channel.go: Channel model with DB access for relation queries
- Database.NewChannel() factory injects db reference into model instances
- Uses interface to avoid circular imports (models -> db)
