When a test leaves a timer running, jest force-stops that worker, prints a warning, and the run still passes. Jest has no option that fails the run instead. Both test scripts in package.json now run jest through script/lib/jest.js. It passes jest's output through and exits 1 when jest printed that warning. Model: opus-5-5
