activitypub_pre_resolve_public_host

Filters the resolved addresses for a hostname before validation.

Returning a non-null array of array{ipv4: string[], ipv6: string[]} skips the DNS lookup. Tests use this to exercise the validation/preference logic without making real DNS queries; production code should leave it null.
