Express 5 exposes req.query through a getter that re-parses the URL on
every read, so the guards' in-place normalization was silently dropped:
?type=caa reached dns-resolver lowercase, ?asn=AS13335 reached the ASN
handlers unparsed, ?q=as13335 missed whois's AS<n> branch. Guards now pin
the parsed query as an own property before rewriting it, and a regression
block exercises them on a real Express request.
Fixes#521
