🐛 Correctness Issue

Test expectation contradicts test purpose.

The test named 'Prints early validation error' now expects no error (undefined), which contradicts its purpose and could mask real errors.

Current Code (Diff):

- 	t.is(getErrorLine(stderr), undefined);
+ 	t.is(getErrorLine(stderr), `${testTimestamp} [0] × TypeError: The "cwd" option must be a string or a file URL: true.`);
