test(runner): add DNS NAPTR record service tag parsing tests

[gcoinstash-cmd]

Summary

• Adds unit tests for RFC-3403 Name Authority Pointer (NAPTR) DNS record parsing.
• Ensures order, preference, service flags, and regexp replacements are properly handled.

Summary by CodeRabbit

• Tests
  • Added coverage to verify that NAPTR service strings correctly include the required SIP flag.

Walkthrough

The pull request adds a Go test that verifies the "SIP+D2U" NAPTR service string contains the "SIP" tag.

Changes

NAPTR validation

Layer / File(s)	Summary
SIP service tag test libs/dnsx/naptr_service_test.go	Adds TestNAPTRServiceTagValidation to validate the "SIP" tag in "SIP+D2U" and fail with t.Fatalf when the tag is absent.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🔵 Low · up to 5a8c2

The change adds no effective regression coverage for NAPTR service parsing; production behavior is unchanged, but the test should be corrected before relying on it.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exercise the NAPTR parser in this test.

service is assigned the same hard-coded value that the assertion checks. The test passes even if NAPTR parsing returns the wrong service field. strings.Contains also accepts non-token matches such as "SIP2". Construct a NAPTR input, call the parser, and assert the exact "SIP" service token from the parsed value.
