 		5d1e5ca86c feat: add comprehensive test suite for ExploreDNS
CI / test (pull_request) Failing after 2m36s
Details 
- Unit tests for all internal packages exceeding 80% coverage:
  - internal/config: 86.2% (ParseMaxDepth, ParseRetries, validation paths)
  - internal/dns: 82.9% (IterativeQueryWithExchange, mock DNS server, roots)
  - internal/fingerprint: 96.4% (unchanged, already excellent)
  - internal/output: 86.7% (formatters, stats, JSON/text output, hooks)
  - internal/traverse: 86.7% (SetHooks, ResolveNS, processReferral,
    ensureRDFalse, resolveGlueViaSystem, newAQuery, Referral.Resolve)

- Integration tests in internal/integration/:
  - End-to-end traversal with mock DNS exchange function
  - Referral chain traversal (root -> TLD -> authoritative)
  - CNAME resolution and loop detection
  - NXDOMAIN and SERVFAIL response handling
  - Max depth enforcement
  - Context cancellation
  - TraverserHooks event delivery

- Mock DNS server helper in internal/dns/roots_test.go using miekg/dns
  (enables deterministic testing without network dependency)

- CI updated with coverage reporting step
- Makefile: added 'cover' target for local HTML coverage reports

- stats.go ComputeSummary: return nil when Answers and ByType are empty
- dns/types.go: remove duplicate ParseQueryType (dead code)
- formatter.go: log hook errors to stderr when Debug > 0; add Debug to Config
- text.go referralID: remove redundant depth==0 branch
- text.go writeServers: remove version lookup placeholder string

Garyandmultica-agent db3ad498f6 feat: implement CachingResolver with per-server query caching
CI / test (pull_request) Failing after 3h13m39s
Details 
Add Resolver interface, BasicResolver, and CachingResolver to internal/dns.

CachingResolver wraps any Resolver with an in-memory cache keyed by
(server IP, name, type, class). Cache entries respect DNS TTL from
responses, falling back to a configurable default TTL. Thread-safe
using sync.RWMutex. Includes Len, Clear, and PurgeExpired methods
for cache management.

Closes HAN-379 (Phase 2.2).

Garyandmultica-agent 924fcbd43a feat: implement root server discovery (HAN-378)
CI / test (pull_request) Failing after 1m17s
Details 
Add RootServer struct and DiscoverRoots function that queries the local
resolver for NS records of the root zone, resolves each root name to
A/AAAA addresses, and returns a list of RootServer structs.

Supports:
- Default: discovers a single root server from local resolver
- --root-server override to target a specific root server
- --all-root-servers to discover all 13 root servers
- --root-aaaa flag to include IPv6 addresses

Includes unit tests for all helper functions and integration tests
that skip gracefully when no resolver is available.

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.
