Vendored DeepSeek V4 TileLang kernels.

Miles DeepSeek V4 kernels

The vendored sparse attention and indexer kernels were adapted from the Miles DeepSeek V4 implementation:

Local modifications include adapting the kernels to AutoModel’s DeepSeek V4 tensor layouts, packed-sequence dispatch, optional backend selection, and forward/backward parity tests against the torch reference implementation.

DeepSeek TileKernels

The Sinkhorn optimized path imports DeepSeek TileKernels at runtime. AutoModel does not vendor TileKernels source code.
