* fix(video): forward --aspect-ratio into the Gemini Veo request The video-generation skill accepts --aspect-ratio and passes it into generate_video(), but the Gemini branch drops the value: _generate_video_gemini has no aspect_ratio parameter and builds the predictLongRunning body with only instances, so every Veo request runs at the default ratio regardless of the CLI flag. Forward the value as parameters.aspectRatio and cover it with a monkeypatch regression test that captures the outgoing request body. * fix(skills): avoid false credential findings in video generation --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>
