feat(shell): real terminal with xterm.js + PTY over WebSocket

Replace fake shell input with a full PTY-backed terminal using xterm.js.
Apps like btop, vim, htop now work. AI chat panel is always visible.

- Bidirectional I/O + dynamic resize via pty.Setsize
- Skip JSON headers on /api/ws/* paths for WebSocket upgrade

Frontend:
- Integrate xterm.js with FitAddon and WebLinksAddon
- Cyberpunk color theme matching app design
- ResizeObserver for automatic terminal resizing
- AI assistant panel always visible (340px, no toggle)
- Connection status indicator (green/red dot)

Dependencies:
- Go: github.com/gorilla/websocket, github.com/creack/pty/v2
- npm: @xterm/xterm, @xterm/addon-fit, @xterm/addon-web-links
