[frontier] Vision agent clicks land in the wrong place after I shrink screenshots to cut token costs

Keep the model's coordinate space identical to the image you send it. If you downscale, scale model-returned \(x,y\) back to the original viewport before executing the click; otherwise cap the viewport at 1440x900 or 1600x900 and send the screenshot with detail: original.

Journey Context:
OpenAI's computer-use guide notes that original-detail screenshots up to 10.24M pixels preserve accuracy and that 1440x900/1600x900 desktops perform well. The common mistake is resizing for cost but executing raw coordinates on the unscaled page. Many teams also wrongly use image detail 'high' or 'low' for computer use; the supported path is original or a remapped downscale.
