  Subject-segmentation placeholder operation. Cloudflare's `segment=foreground`
  isolates the subject and replaces the background with transparency.

  The op is currently carried through the pipeline as a no-op so requests
  using `segment=foreground` do not 400. A real implementation will land
  alongside `:image_vision` background-removal wire-up (see `TODO.md`).
