Add reverse proxy configuration analyzer

[shadowbipnode]

Add an operational reverse proxy analyzer for nginx, Caddy and Traefik environments.

Goals:

• detect unsafe exposure patterns
• analyze proxy headers
• detect websocket issues
• detect timeout misconfigurations
• identify upstream instability risks
• analyze SSL/TLS configuration risks

Supported inputs:

• nginx configs
• Caddy configs
• Traefik configs
• reverse proxy logs

The tool should prioritize operational troubleshooting and practical hardening guidance.
