Verified on GB200: both FastVideo/DreamX-World-5B-Cam-Diffusers and
FastVideo/DreamX-World-5B-Diffusers strict-load from the Hub with no
missing/unexpected keys, and the Cam example generates a video end-to-end
from the Hub repo id.
- registry: hf_model_paths now reference the published FastVideo Diffusers
repos instead of the official GD-ML checkpoints (which are raw-format and
not directly loadable).
- example + support matrix: default/documented model ids updated likewise.
- SSIM test: model paths default to the Hub repos like sibling SSIM tests;
the local-converted-path skip machinery is gone (env overrides remain).
