720p + upscaled 81 images new VAE Decode

### Feature Idea

We are utilizing Wan, which is excellent, but many components are offloaded to the main memory. Before processing VAE Decode, I would like the Clip model to be purged from the main memory. If the offloaded data is not purged, the process often gets killed when VAE Decode starts.

It is acceptable to switch VAE Decode to virtual memory processing primarily based on an M.2 disk. Since nearly HD 80 images are processed simultaneously, I want to avoid process termination using either of these ideas.
