Domain enrichment profile (RDAP + DNS join) API

Given a domain, JOIN several keyless sources into one enrichment record an agent would otherwise need 3+ calls for: RDAP (registrar, creation/expiry dates, age) + DNS (A/MX/NS/TXT presence) + a derived signals block (email-capable via MX, domain-age bucket, DNSSEC, SPF). The value-add is the multi-source merge into a single clean profile. Answers 'enrich this domain','is this domain email-capable','how old is this domain','who is the registrar'.
