feat(core): recursive DNS server after Java, measured with Java FILIUS
The resolver runs on the events now (a query, its dnsQueryTimeout, its answer at the socket); the blocking resolveDns waits for it, and a recursive server uses it: its own records, else the zone's name server from its records, else its own DNS server, else a referral (DNSServer.answerWithRemoteData). DnsRun plays five stories on the new dns-recursive network. Measured and not taken: a server that is its zone's name server asks itself, which asks itself again, without end (the client times out, then every level floods its own DNS server); Java guards only the step through its own DNS server. The core asks itself in neither step. That story is compared up to the client's query (JAVA_UNTIL). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
