Closes HAN-401

Adds RespNSResolutionFailed response type to clearly distinguish in-bailiwick nameserver resolution failures from actual domain errors.

Changes:

  • traverse/response.go — new RespNSResolutionFailed type ("ns_error") included in IsTerminal() and String()
  • traverse/traverser.go — processReferral returns RespNSResolutionFailed instead of bare RespError; ResolveNS dispatch loop handles the new type; deduplicated nsName extraction
  • output/stats.go — "ns_error" maps to "nameserver lookup failed"
  • output/text.go — RespNSResolutionFailed displays in yellow (not red)

All tests pass.

Closes HAN-401 Adds `RespNSResolutionFailed` response type to clearly distinguish in-bailiwick nameserver resolution failures from actual domain errors. **Changes:** - `traverse/response.go` — new `RespNSResolutionFailed` type (`"ns_error"`) included in `IsTerminal()` and `String()` - `traverse/traverser.go` — `processReferral` returns `RespNSResolutionFailed` instead of bare `RespError`; `ResolveNS` dispatch loop handles the new type; deduplicated `nsName` extraction - `output/stats.go` — `"ns_error"` maps to `"nameserver lookup failed"` - `output/text.go` — `RespNSResolutionFailed` displays in yellow (not red) All tests pass.

output: distinguish nameserver resolution failures from domain errors beefaf44e0 
When an in-bailiwick nameserver cannot be resolved (no glue records and
iterative resolution fails), the traversal previously returned a generic
RespError. This made the Results section show many identical '6.7%
resulted in an error' lines and the Summary show '100% resulted in an
error' — even though the domain itself may be perfectly reachable in
practice via glue held by the registry.

Add a new RespNSResolutionFailed response type (string: ns_error)
for this specific case. Changes:

- traverse/response.go: add RespNSResolutionFailed, include it in
  IsTerminal() and String()
- traverse/traverser.go: use RespNSResolutionFailed with a descriptive
  ErrorMessage when ResolveNS fails in processReferral
- output/stats.go: map ns_error to nameserver lookup failed in
  summaryTypeLabel
- output/text.go: handle RespNSResolutionFailed in formatResultLine

Before:
  Results:     6.7% resulted in an error (x15)
  Summary:   100% resulted in an error

After:
  Results:     6.7% nameserver ns-a.hansenits.com.au could not be resolved (x15)
  Summary:   100% nameserver lookup failed

traverse: apply code review fixes in ResolveNS dispatch loop

- Add RespNSResolutionFailed to the error-type guard in ResolveNS so
  nameserver resolution failures are treated consistently with SERVFAIL
  and RespError (skip + continue rather than fall through).
- Deduplicate nsName extraction before the err/len branches so it is
  computed once instead of twice.
