Krea K3 Edit API — instruction-based image editing from $0.17

Krea K3 Edit is an image-to-image editing model from Krea. You send an image plus a text instruction and it returns a single edited image. It does not generate from a prompt alone: requests without an input image in `imageData` are rejected.

On YepAPI you submit edits to `/v1/media/queue` with the image as base64 in `imageData`, at about $0.17 per image. Generate a starting image on Krea 2 and refine it on K3 Edit with the same key.
