RDAP domain pivot API

Resolve a domain via the keyless RDAP protocol to registrar, registrant org, nameservers, and status, then surface pivot leads (reverse-nameserver and reverse-registrant) for chasing related domains. The value-add is the relationship surfacing: unwinding RDAP's entity/vcard graph, normalizing nameservers to their apex providers, and emitting ready-to-run pivots without fabricating data. Answers 'who registered this domain', 'nameservers of X', 'what is the registrar', 'how do I pivot to related domains from this one'.
