 		6e9aefc47e feat: complete Phase 4.1 error handling and robustness (HAN-385)
CI / test (pull_request) Failing after 2m41s
Details 
- Fast mode cache isolation: TraverserConfig.Fast=false gives each
  referral its own independent InfoCache with no cross-branch glue
  inheritance; Fast=true (default) retains the shared root cache so
  earlier branch discoveries are reused
- Wire cfg.Fast from CLI config into TraverserConfig in main.go
- IDN/Punycode: NewReferral now converts unicode domain labels to their
  ACE/punycode form via golang.org/x/net/idna before querying, with a
  graceful fallback when conversion fails
- DNSSEC: hasFinalAnswer() now skips RRSIG records alongside CNAME so
  a signed referral does not prevent CNAME following
- Tests: DNSSEC RRSIG does not block CNAME follow, fast/non-fast cache
  isolation, 12-NS referral, IDN conversion, wildcard answer, long CNAME
  chain depth limit, partial branch failure with graceful degradation

 		368f200d23 Phase 4.1: Error handling, edge cases, and robustness
CI / test (pull_request) Failing after 3m40s
Details 
- Exponential backoff retry logic (100ms, 200ms, 400ms... capped at 2s)
  replacing fixed 100ms delay between retries
- Explicit REFUSED and NOTIMP response types (RespREFUSED, RespNOTIMPL)
  surfaced as terminal results with user-visible messages
- CNAME loop detection: walking the ancestor referral chain before
  following a CNAME prevents infinite recursion; produces RespCNAMELoop
- DNAME record support: synthesize CNAME target from DNAME mapping when
  the server omits the RFC 6672 synthesized CNAME record
- ErrorMessage field on Response for surfacing error details to users
- Fix resolveGlueViaSystem timeout bug: deadline.Sub(deadline) was
  always 0; replaced with time.Until(deadline)
- DNAME records excluded from hasFinalAnswer so DNAME-only responses
  are correctly classified as RespCNAMEFollow
- Text and JSON output updated with labels for all new response types
- Tests: CNAME loop (2-step and direct), REFUSED, NOTIMP, graceful
  degradation (partial and total server failure), DNAME synthesis,
  IsNameInChain, backoffDelay, ResponseClassification strings

CI / test (pull_request) Waiting to run
Details 
- gofmt main.go to fix tab indentation in main() body
- 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
