Check whether an email address has a Gravatar: hashes the normalized email (MD5, pure CPU - the raw address is never sent upstream), probes gravatar.com for an avatar, and fetches the public profile when one exists (display name, username, profile URL). Accepts a raw email or a precomputed MD5/SHA-256 hash. Signal-only: a Gravatar's existence suggests a real, web-active address but does NOT verify identity or deliverability - pair with /api/email-validate for MX checks.
