Server: forward canvas/reference images to the image model so extract,
continue, and edit requests stay faithful to the source product.
- Add ImageRequestOptions.Images and route requests with inputs to the
/v1/images/edits endpoint, via multipart upload (default) or JSON
image_url payload, selectable through Agent.Image.InputImageTransport.
- Extract reference URLs from prompt directives, inline @image tokens,
and chat message image/mask contents; fold them into the idempotency
key and prepend a reference-fidelity instruction to the prompt.
Frontend:
- Shrink CanvasToast to a compact top pill.
- Paste an internal transparent clipboard node instead of re-uploading
when it matches the clipboard image.
- Keep agent-project polling alive on stream error while streaming.
