Garyandmultica-agent	2835ee86cf	feat: implement Phase 2.3 DNS traversal engine ... Add core traversal engine with iterative resolution from root servers: - referral.go: Referral struct with name, type, bailiwick, addresses, state - cache.go: Chained InfoCache with parent inheritance for NS and glue records - stack.go: LIFO stack with configurable max depth enforcement - response.go: Response classifier (referral, answer, CNAME follow, NODATA, NXDOMAIN, SERVFAIL) with child referral generation and probability splitting - traverser.go: Traverser orchestrates full traversal from root to leaf, following all referral branches, handling CNAME chains, and respecting max depth limits Add IterativeQuery/IterativeQueryWithExchange to dns package (RD=false queries). 57 new tests covering all acceptance criteria: traversal from root to leaf, comprehensive branch following, max depth enforcement, probability distribution, chained cache behavior, CNAME following, NXDOMAIN/SERVFAIL handling, context cancellation, and concurrent access.

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.
