Complete feature parity with Docker deployment:
- Caddy reverse proxy manages SSL/TLS
- Ports: 8916/8917 (HTTP), 8918/8919 (HTTPS)
- Self-signed certificates (development-friendly)
- Automatic certificate generation via on-demand TLS
- Security headers (HSTS, XSS Protection, etc.)
Changes:
- Created Caddyfile.standalone for localhost config
- Enhanced start_servers.py with Caddy startup/monitoring
- Auto-install Caddy via apt if not present
- Updated status output to show both HTTP and HTTPS URLs
- All three services (backend, frontend, caddy) in one launcher
Both Docker and Standalone modes now have IDENTICAL capabilities:
- Full production-ready SSL/TLS support
- Reverse proxy with auto-certificate management
- HTTPS-only capable
Resolves dual-deployment equivalence requirement
