Adds 'HTTPS' to the DnsRecordType union so DNS check constructs can monitor a domain's HTTPS service-binding record (HTTP/3 advertisement via alpn, plus ipv4hint/ipv6hint/ech). Updates the DnsAssertionBuilder @example to the recommended assertion forms.

What
Adds the HTTPS (RFC 9460, DNS type 65 / SVCB family) record type to the DNS check construct's
DnsRecordTypeunion, so monitoring-as-code can query a domain's HTTPS service-binding record — e.g. verify HTTP/3 advertisement (alpn), IP hints (ipv4hint/ipv6hint), or ECH.Changes
constructs/dns-request.ts— add'HTTPS'toDnsRecordType, with a doc note on therecordTypefield.constructs/dns-assertion.ts— update theDnsAssertionBuilder@exampleto the recommended forms:DnsAssertionBuilder.textAnswer('alpn="([^"]*)"').contains('h3')(capture group scopes the match to the alpn value)DnsAssertionBuilder.jsonAnswer('$.Answer[0].data').contains('alpn="h3')Context
Pairs with the runner + API support and the webapp record-type option in the main monorepo (runner/API and webapp PRs). The runner renders the HTTPS record's rdata into the answer (
1 . alpn="h3,h2" ipv4hint="…" …), which these assertions target.
