As a user
I want to view mainline in a web browser
So that I can display on devices without terminal

Acceptance Criteria:

WebSocket server on port 8765 broadcasts frames
HTTP server on port 8766 serves HTML client
Client renders ANSI colors on HTML5 Canvas
Fullscreen support in browser

Technical Tasks:

Create engine/display/backends/websocket.py: WebSocketDisplay
Create client/index.html: Browser client with ANSI parsing
Update engine/display/__init__.py: Registry discovers websocket
Add tests: test_websocket.py, test_websocket_e2e.py
