Phase 1 MVP: gateway, CRUD handlers, frontend components

Backend:
- WebSocket gateway (hub, client, events) with fanout broadcast
- Server CRUD handlers (create, list, get, update, delete)
- Channel CRUD handlers (create, list, get, update, delete)
- Message CRUD handlers (list with cursor pagination, create, update, delete)
- cmd/migrate standalone migration CLI (up/down)
- cmd/server wired to all handlers + WebSocket + static file serving

Frontend:
- Zustand stores: auth, server, channel, message, websocket
- API client with fetch wrapper
- Terminal-styled components: Layout, LoginForm, ChatArea, ChannelList, ServerBar, MemberList
- React Router with login and main routes
- Gruvbox dark palette throughout

Ops:
- Docker Compose with app service (multi-stage build)
- Caddyfile with WebSocket upgrade support
- Makefile for common tasks
