Remote VAE feedback

### Did you like the remote VAE solution?

Absolutely, it is amazing for us AMD users. Until they figure out whatever bug is causing super long vae decode/encodes with AMD cards.. This solution is perfect. Who knows if its even a bug, its been happening for quite a while now unfortunately.

### What can be improved about the current solution?

An official comfyui node would be cool to see, so it can be instantly updated for new vaes in the future (hopefully)

### What other VAEs you would like to see if the pilot goes well?

WAN would be awesome, videos are all the rage now and currently I have to used tiled vae or its impossible to do WAN videos with my AMD.

### Notify the members of the team

@hlky @sayakpaul Thanks for your hard work on this!

The issue names no files, tests, or entry points. First clarify the scope of an official ComfyUI node and WAN VAE support, then identify the existing remote VAE implementation and its update path; done should include an agreed integration design and verification for AMD users.
