Use process.once('beforeExit') instead of process.on('exit').

Replaced the event listener to ensure cleanup runs once before exit instead of during the exit phase. Removed redundant `finally` block handling cleanup to avoid potential conflicts with the updated listener logic. Also, 'beforeExit' event does not fire if process.exit() was called explicitly or in case of other "unexpected" issue, so, we will be able to debug the issue inside temp dir
