By default, this opens URLs with the browser picker. You can customize the behavior
with flags to handle different MIME types or application categories.

Examples:
  dms open https://example.com                    # Open URL with browser picker
  dms open file.pdf --mime application/pdf        # Open PDF with compatible apps
  dms open document.odt --category Office         # Open with office applications
  dms open --mime image/png image.png             # Open image with image viewers`,
