Reverted to commit 36b439e's NVFP4 kernel code:
- kGranK=16, mxf4nvf4.block_scale.scale_vec::4X
- float_ue4m3_t instruction descriptor
- Block16 SF layout (4X TMEM)
- UE4M3 L1 epilogue
- No UE4M3→UE8M0 conversion, no block16→block32 merge
The mxf4nvf4.scale_vec::4X PTX instruction compiles successfully
on both sm_100 and sm_100f with CUDA 13.0. The previous build 17
error was likely from a different cause, not the arch flag.
Python: reverted transform_nvfp4_weights_for_mega_moe to use
pack_ue4m3_to_int32 with gran_k=16, no UE8M0 conversion.
