Garyandmultica-agent	fce7920611	feat: add DNS query/response layer with miekg/dns ... Phase 1.2 implementation: - internal/dns/types.go: DNS record type constants (A, AAAA, NS, CNAME, SOA, MX, TXT, SRV, PTR, ANY) with QNameType helper and EDNS0 defaults - internal/dns/query.go: Query/QueryWithExchange with UDP, configurable EDNS0 buffer size, TCP fallback on truncation, always-TCP mode, configurable retries with timeout, context support, and injectable ExchangeFunc for testing - internal/dns/decode.go: Response classification (answer, referral, NODATA, NXDOMAIN, SERVFAIL), CNAME chain extraction with dedup, truncation/RCODE detection, and section extraction utilities 32 unit tests covering all acceptance criteria.
