Fetch a URL and grade its HTTP security headers: CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and COOP/CORP. Returns a 0–100 score, a letter grade, and a concrete recommendation for every missing header. Use this when an agent needs to grade a site's HTTP security headers + fix hints.
