Research direction
Investigate why jest cli is not found after eject. The error trace shows it's trying to require from the jest package. Check the jest version used by react scripts ts and ensure it's properly listed in package.json. Possibly a missing dependency or hoisting issue. Look at the scripts/test.js file and the jest cli path.
