Subject: [PATCH] feat: add Docker GUI support with VNC and noVNC

Adds Dockerfile.gui with Xvfb, VNC, and noVNC for running the bot
with a visible browser in Docker:
- Xvfb virtual framebuffer for headless display
- x11vnc for VNC access
- noVNC for browser-based access at http://localhost:6080
- Playwright chromium with system dependencies
- docker-compose.gui.yml for easy startup
