Improved Directory Handling

The isDirEmptySync function now includes an existence check before checking if a directory is empty. This prevents errors when working with non-existent directories.

// Old behavior: Would error if directory doesn't exist
function isDirEmptySync(path) {
  return fs.isDirEmptySync(path);
}

// New behavior: Returns true for non-existent directories
function isDirEmptySync(path) {
  if (!fs.existsSync(path)) return true;
  return fs.isDirEmptySync(path);
}
