docs: save working nginx config for rommark.dev

Complete nginx configuration with proper WebSocket support:
- Added connection_upgrade map for WebSocket upgrade handling
- Configured /claude location with proper WebSocket headers
- Set extended timeouts (7d) for WebSocket connections
- Disabled buffering for real-time communication

This config fixes the WebSocket closure issue that was preventing
terminal commands from being executed.
