SolitaryThinker c426847cb6 [bugfix]: FastWan-QAD weights moved to transformer/ on HF — try both paths 
The pinned generator_inference_transformer/ path now 404s; the repo
ships transformer/diffusion_pytorch_model.safetensors. Found during
the GB200 FLASHINFER_SAGE_ATTN3 shape-collection run.

SolitaryThinker 73b56f0a63 [feat]: FlashInfer SageAttention3 backend + attention shape logging 
Adds FLASHINFER_SAGE_ATTN3 wrapping flashinfer's dense SM120 NVFP4
attention (flashinfer-ai/flashinfer#3640), falling back to torch SDPA
with one warning when flashinfer/SM120 is unavailable, and an env-gated
JSONL attention shape logger (FASTVIDEO_ATTN_SHAPE_LOG) hooked into the
new backend and SAGE_ATTN_THREE to collect real workload shapes for
SM121 (DGX Spark) kernel tuning.
