Enforce `QUEUE_MAX_AGE` and `MAX_HISTORY` config values that previously existed but were not applied.
The existing cleanup loop now also:
- **Prunes `client_queues`** entries older than `QUEUE_MAX_AGE` (default 48h / 172800s)
- **Rotates `messages`** per target (channel or DM) beyond `MAX_HISTORY` (default 10000)
- **Removes orphaned messages** no longer referenced by any client queue
All pruning runs inside the existing periodic cleanup goroutine at the same interval as idle-user cleanup.
### Changes
- `internal/config/config.go`: Added `QueueMaxAge` field, reads `QUEUE_MAX_AGE` env var (default 172800)
- `internal/db/queries.go`: Added `PruneOldQueueEntries`, `PruneOrphanedMessages`, and `RotateChannelMessages` methods
- `internal/handlers/handlers.go`: Added `pruneQueuesAndMessages` called from `runCleanup`
- `README.md`: Updated data lifecycle, config table, and TODO checklist to reflect implementation

Add CSP header to all HTTP responses for defense-in-depth against XSS.
The policy restricts all resource loading to same-origin and disables dangerous features (object embeds, framing, base tag injection). The embedded SPA requires no inline scripts or inline style attributes (Preact applies styles programmatically via DOM properties), so a strict policy without `unsafe-inline` works correctly.
**Directives:**
- `default-src 'self'` — baseline same-origin restriction
- `script-src 'self'` — same-origin scripts only
- `style-src 'self'` — same-origin stylesheets only
- `connect-src 'self'` — same-origin fetch/XHR only
- `img-src 'self'` — same-origin images only
- `font-src 'self'` — same-origin fonts only
- `object-src 'none'` — no plugin content
- `frame-ancestors 'none'` — prevent clickjacking
- `base-uri 'self'` — prevent base tag injection
- `form-action 'self'` — restrict form submissions

## Summary
When closing and reopening the SPA, channel tabs were not restored because the client relied on localStorage to remember joined channels and re-sent JOIN commands on reconnect. This was fragile and caused spurious JOIN broadcasts to other channel members.
## Changes
### Server (`internal/handlers/api.go`, `internal/handlers/auth.go`)
- **`replayChannelState()`** — new method that enqueues synthetic JOIN messages plus join-numerics (332 TOPIC, 353 NAMES, 366 ENDOFNAMES) for every channel the session belongs to, targeted only at the specified client (no broadcast to other users).
- **`HandleState`** — accepts `?replay=1` query parameter to trigger channel state replay when the SPA reconnects.
- **`handleLogin`** — also calls `replayChannelState` after password-based login, since `LoginUser` creates a new client for an existing session.
### SPA (`web/src/app.jsx`, `web/dist/app.js`)
- On resume, calls `/state?replay=1` instead of `/state` so the server enqueues channel state into the message queue.
- `processMessage` now creates channel tabs when receiving a JOIN where `msg.from` matches the current nick (handles both live joins and replayed joins on reconnect).
- `onLogin` no longer re-sends JOIN commands for saved channels on resume — the server handles it via the replay mechanism, avoiding spurious JOIN broadcasts.
## How It Works
1. SPA loads, finds saved token in localStorage
2. Calls `GET /api/v1/state?replay=1` — server validates token and enqueues synthetic JOIN + TOPIC + NAMES for all session channels into the client's queue
3. `onLogin(nick, true)` sets `loggedIn = true` and requests MOTD (no re-JOIN needed)
4. Poll loop starts, picks up replayed channel messages
5. `processMessage` handles the JOIN messages, creating tabs and refreshing members/topics naturally

## 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.
