fix(signals): single-source isCodeFile via isSourcePath and add .kts

[RealDiligent]

Summary

• Add isSourcePath in test-evidence.ts as the canonical source-side matcher symmetric with isTestPath for JVM/.NET/Swift/Groovy/Kotlin-script files.
• Delegate path-matchers.ts and engine.ts isCodeFile to isSourcePath (plus the existing extended native/front-end/Dart extensions) so the classifiers cannot drift.
• Recognize .kts Gradle Kotlin-script source so untested changes no longer escape missing-tests gate signals.

No linked issue: classifier symmetry bugfix — isTestPath already recognizes .kts test files, but isCodeFile omitted .kts source, letting untested Gradle Kotlin-script changes bypass missing-tests gates. Small, self-contained fix with regression tests only.

Validation

• npm test -- test/unit/test-evidence.test.ts test/unit/local-branch-file-classifiers.test.ts test/unit/path-matchers.test.ts test/unit/signals.test.ts (138 tests passed locally)
• CI validate-code + validate green on this PR

Safety

• No secrets, auth, API, UI, or migration changes.
• Behavior-preserving for previously-covered extensions; only adds .kts source and consolidates duplicate matchers.

🛑 Suggested Action - Reject/Close

• No linked issue detected — If this PR is intended to solve an issue, link it explicitly in the PR body.
• Maintainer requires a linked issue — Link the relevant issue (for example Closes #123) before opening the PR.
• AI reviewers agree on a likely critical defect: The PR description explicitly states 'No linked issue' — this repo's contributor policy requires every external PR to close or clearly link an eligible open issue before merge, and none is provided here. — Resolve the flagged defect, or override if the AI reviewers are mistaken, then re-run the gate.

Review summary
This PR consolidates isCodeFile logic in path-matchers.ts and engine.ts to delegate to a new isSourcePath in test-evidence.ts, adding .kts recognition so Kotlin-script source is correctly flagged for missing-tests gates. Tracing the regex unions confirms the new isSourcePath (core set) plus EXTENDED_SOURCE_EXTENSION in path-matchers reproduces the old combined extension list exactly, with .kts added — the stated fix. As a side effect, engine.ts's isCodeFile now also picks up path-matchers' generated-Dart-part exclusion (.g.dart/.freezed.dart/.gr.dart), which the old engine.ts local copy lacked; this is a real behavior change beyond the .kts fix, but it's intentional (removes a documented drift) and is covered by a new regression test in signals.test.ts.

Blockers

Nits — 5 non-blocking

• src/signals/path-matchers.ts:24 references issue fix(signals): exclude generated Dart part files from code scoring #3724 only in a comment; consider a named constant or explicit link if that context matters long-term.
• The behavior change where engine.ts's isCodeFile now excludes generated Dart part files (previously it did not) is a second, distinct fix bundled with the .kts addition — worth calling out explicitly in the PR description rather than only in code comments, since it changes missing-tests-gate behavior for an unrelated language ecosystem.
• test-evidence.ts's isSourcePath and path-matchers.ts's EXTENDED_SOURCE_EXTENSION split the same conceptual 'source extensions' list across two files/regexes; a single exported list of extensions consumed by both would remove the last bit of duplication this PR is trying to eliminate.
• Link or open a tracking issue for this classifier-symmetry bug per repo contribution policy before merge.
• Call out the Dart-generated-file exclusion behavior change for engine.ts explicitly in the PR description, since it's a second fix riding along with the .kts addition.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
