CLIP-Guided Diffusion — ZeroGPU AOTI compiler

Compiles one full guided DDPM timestep (512px, cutn 16, bf16, 4 prompt slots; schedule + guidance scales are graph inputs, so one package serves any steps/scales) for each backbone missing from multimodalart/clip-guided-diffusion-aoti-zerogpu (ViT-B/16, ViT-B/32, ViT-L/14, google/siglip2-large-patch16-256). Configs already matching this torch version are skipped. Needs the HF_TOKEN secret (write).
