compare_images	Changed pixels between two equal-size images. No OCR.

CLI: iris · SDK: @sylphx/iris/sdk · composition with companion tools is through public MCP and SDK contracts only.

fast, or no profile, does not run OCR. Explicit include_ocr: false wins over quality. A missing Tesseract binary leaves status at ok and adds OCR_UNAVAILABLE to gaps.
