Crate baracuda_cutensor_sys 

Raw FFI + dynamic loader skeleton for NVIDIA cuTENSOR.

baracuda-cutensor wraps this with a safe, typed API. Use this crate directly only if you need a function that the safe layer hasn’t wrapped yet (in which case please file a bug).

cuTENSOR is a separately-installed NVIDIA library for high-performance tensor contraction, reduction, and element-wise ops. v0.1 ships the loader + status enum; concrete contraction/permutation/reduction wrappers follow once CI has a cuTENSOR install.
