• New internal/whois/tlds.go holds per-TLD WHOIS server, query format, and response normalizer in one map.
• .de: send -T dn <domain> so DENIC returns nameservers and changed date.
• .jp: query JPRS with /e and normalize bracketed labels into key: value form.
• .it: parser handles bare section headers with indented sub-fields, so registrar info no longer collides with registrant info.
• .org: strip URL schemes/ports from registrar referral hosts so we actually reach the registrar WHOIS.
• Resolver runs RDAP and WHOIS in parallel and merges them; RDAP wins where both have data.
