Store and restore the original TMPDIR value using a deferred function in `msg_nowin_test.go`. This ensures the TMPDIR environment variable is restored after the test runs, preventing potential side effects on other tests or processes.
This new test verifies error handling for WriteToTempFile when the TMPDIR environment variable is set to an invalid directory. It ensures that the method fails as expected under these conditions, improving code robustness.
