THEN Modify the path validation logic to perform case-insensitive comparison on Windows. Before checking if a parent path starts with an allowed directory, convert both the normalized parent path and the allowed directory to lowercase (or use a case-insensitive method) when `process.platform === 'win32'`. This ensures drive letters and path components match regardless of case.

// In the allowed directory check:
const isParentAllowed = allowedDirectories.some(dir => {
  if (process.platform === 'win32') {
    return normalizedParent.toLowerCase().startsWith(dir.toLowerCase());
  }
  return normalizedParent.startsWith(dir);
});
