DnsResolve_4_one
Description
Spec-based overload (single-addr form). Same parse path as the vec form, but only the first matching SocketAddr is written back – the “getaddrinfo + pick first” idiom in one call so callers needing exactly one address (typical for SocketConnect / ListenerOpen) don’t have to manage a throwaway Vec.
Success
Returns true; out populated.
Failure
Returns false; out untouched.
