/**
 * DNS Addon
 *
 * Validates that DNS records resolve to the expected targets.
 * Does NOT call any DNS provider API — works with any provider (Dynu, Cloudflare, etc.)
 *
 * ============================================================
 * USAGE
 * ============================================================
 *
 * Configure in stack.yml:
 *
 * dev:
 *   domain: dev.example.com
 *   plugins:
 *     dns:
 *       records:
 *         - host: ""          # root domain → Vercel
 *           target: cname.vercel-dns.com
 *         - host: api         # api.dev.example.com → AWS ALB
 *           target: my-alb.us-east-1.elb.amazonaws.com
 *
 * On scan: does DNS lookup, warns if records don't match expected targets.
 * On fix: shows what needs updating, acknowledges warning in stackAuto.yml.
 *         Re-checks automatically if target changes in stack.yml.
 * ============================================================
