What's New

DNS error classification

The tool now distinguishes between missing records (NOTFOUND/NODATA) and DNS infrastructure errors (SERVFAIL, TIMEOUT, CONNREFUSED).

Previously, all DNS failures were silently treated as "record missing," producing false negatives — if your DNS was flaky, you'd be told "SPF missing, DKIM missing, DMARC missing" when the records might actually exist.

DNS errors now deduct only -5 points (instead of -25/-20/-25 for missing records)
Errors are reported with severity high so CI mode (--ci) still catches them
New isDnsNotFound() and getDnsErrorMessage() utilities exported for programmatic use
Error status icon (!) in table output
