7. Provides Summary: Shows deployment details and useful commands

Example nginx Configuration Generated

# Upstream for my-app Production
upstream my-app_prod {
    ip_hash;
    server 127.0.0.1:3000;
}

# HTTP Server Block
server {
    listen 80;
    server_name my-app.example.com;

    client_max_body_size 20M;
    charset utf-8;

    # Custom error pages
    error_page 404 /not-found;
    error_page 500 502 503 504 /bad-request;

    location / {
        proxy_pass http://my-app_prod;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
