Add DNS responder that resolves <npub>.fips queries to FipsAddress IPv6 addresses. Resolution is pure computation (npub → NodeAddr → IPv6) with identity cache priming as a side effect, enabling subsequent TUN packet routing to non-peer destinations. - New dns.rs module: resolve_fips_query(), handle_dns_packet() using simple-dns crate, run_dns_responder() async UDP server loop - DnsConfig in config.rs: enabled, bind_addr (127.0.0.1), port (5354) - Fourth select! arm in RX event loop for DNS identity channel - DNS task spawn/abort in node lifecycle - 10 new tests (420 total) Add examples/two-node-udp/ with standalone walkthrough for testing two FIPS nodes in Linux network namespaces over a veth pair. Includes network diagram, config files, DNS routing setup, and troubleshooting.
