Inspect URL response

Resolves a public URL through bounded redirects and returns status plus a safe allowlist of HTTP headers. Use HEAD for cheap reachability/type checks and GET when a server mishandles HEAD. Use extract_metadata for HTML semantic metadata. Limit: 8 s, 5 redirects, 768 KiB only for GET.
