The hashcash proof-of-work implementation was incorrectly added to the
build artifact web/dist/app.js instead of the source file web/src/app.jsx.
Running web/build.sh would overwrite all hashcash changes.
Changes:
- Add checkLeadingZeros() and mintHashcash() functions to app.jsx
- Integrate hashcash into LoginScreen: fetch hashcash_bits from /server,
compute stamp via Web Crypto API before session creation, show
'Computing proof-of-work...' feedback
- Remove web/dist/ from git tracking (build artifacts)
- Add web/dist/ to .gitignore
## 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

## 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

## Summary
Complete UI overhaul of the embedded web SPA to look and feel like a proper IRC client.
## Changes
### Layout & Structure
- **Tab bar** at top with channel/DM/server tabs and unread indicators
- **Topic bar** below tabs for channel windows
- **Messages panel** with classic IRC message formatting
- **User list** on right side for channels with @/+/regular prefixes
- **Persistent input line** at bottom with IRC-style prompt `[nick] #channel >`
### IRC Commands
Full command support in the input line:
- `/join #channel` — Join a channel
- `/part [reason]` — Part the current channel
- `/msg nick message` — Send a private message
- `/me action` — Send a CTCP ACTION
- `/nick newnick` — Change nickname
- `/topic [text]` — View or set channel topic
- `/mode +/-flags` — Set channel modes
- `/quit [reason]` — Disconnect
- `/help` — Show available commands
### Message Display
- Messages on the **same line** as the nick: `[HH:MM:SS] <nick> message text`
- System messages: `[HH:MM:SS] * alice has parted #channel (reason)`
- Actions: `[HH:MM:SS] * alice waves hello`
- IRC vocabulary throughout ("parted" not "left", etc.)
### User List
- Right-side panel showing channel members
- Sorted by mode: `@operators` first, then `+voiced`, then regular users
- Click to open DM
- Parses RPL_NAMREPLY (353) for mode prefixes when available
### Other
- Input history with up/down arrow keys
- Dark theme with monospace font (classic IRC aesthetic)
- CTCP ACTION support (`/me`)
- RPL_TOPIC (332) parsing for server-sent topics
- Responsive: user list hidden on narrow screens

## Problem
The SPA fails to load with:
```
Uncaught Error: Dynamic require of "preact" is not supported
```
The esbuild config in `web/build.sh` had `--external:preact`, which tells the bundler to leave preact as a `require()` call instead of including it in the bundle. Since the browser has no `require()` function and there is no CDN/import-map loading preact externally, the app crashes immediately.
## Fix
- Remove `--external:preact` from `build.sh` so preact is bundled into `app.js`
- Add `--format=esm` to output proper ESM instead of IIFE with CJS require shims
- Update `index.html` to use `<script type="module">` for ESM compatibility
- Remove the dead fallback build command (was never reached since the first command succeeded)
- Rebuild `dist/app.js` with preact properly inlined (21.1KB minified)

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
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
