Subdomain Finder: Certificate Transparency

Enumerate every subdomain of a domain from public Certificate Transparency logs. No brute-force wordlist and no DNS hammering, because every TLS certificate is logged, so the hosts are already public record. Deduplicated to one row per hostname, with first seen, issuing CA and current validity.
