Description

#4197 notes that #4091 and #4187 broke some harness tests, which should have been surfaced sooner. I think we should update the package.json test:diff:… scripts to include all test/harness/*.js files whenever harness/ includes any changes.

Research direction

Start in package.json by reading the test:diff:* scripts, then inspect the harness/ and test/harness/*.js paths mentioned in the issue. Update the scripts so harness tests run when harness sources change, and verify the diff-test commands cover those cases.
