- Closes #1268. - The types we were using weren't very usable with Swift 6 structured concurrency. - Implements just the subset of records that we use. - Use notImplemented instead of formatError for unknown record types. - Use pure actor for LocalhostDNSHandler now that we have sendable types. - Use DNSName as key for table lookups in LocalhostDNSHandler and HostTableResolver. - Utilize dot-suffixed domain names everywhere in the lookup chain. - Huge thanks to @manojmahapatra and @katiewasnothere for their diligent and patient review :D
