5d1e5ca86c feat: add comprehensive test suite for ExploreDNS
CI / test (pull_request) Failing after 2m36s
- 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

Garyandmultica-agent db3ad498f6 feat: implement CachingResolver with per-server query caching
CI / test (pull_request) Failing after 3h13m39s
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).
