yarn test-commit-records is not run in CI #8972

Found by differential semantic drift analysis from a7721303 to b123b7c3.

What is broken

The semantic diff renderer's tests run nowhere in CI.

• package.json L66 defines test-commit-records (node --test scripts/commitRecords.test.js scripts/recordMarkdown.test.js). No workflow, Makefile target or scripts/test.js step runs it; semantic_diff.yml only renders.
• By contrast scripts/changelog.test.js runs in changelog.yml L31 and yarn test-release-plan in ci.yml L194.

#8908, #8929 and #8958 each extended these tests; a pull request that breaks parseRecord or the Markdown comment passes CI and shows up only as wrong pages or comments on other pull requests. Open #8962 adds another test file to the same script, still without a CI step.

Possible cause (speculation only)

A guess: the tests were added as a local command when the renderer was introduced, and the later pull requests extended them without noticing that CI does not run them.
