ByteDance Doubao video generation model
Use model parameter to select doubao-seedance-1-0-pro-fast or doubao-seedance-1-0-pro-quality model
Supports text-to-video generation
Supports first frame / last frame / reference image control
Async task management, query results by task ID

Important Change: For better performance and cost control, we no longer support passing base64 image data directly in image_urls. Please use the Upload Image API first to upload images and get URLs, then call this endpoint.
