CI / test (pull_request) Failing after 2m40s
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.
