Module cuda_min 

2026-09-25: Minimal CUDA driver-API FFI for metrale-storage: context and stream, device and pinned host buffers, async copies, stream sync.

Owner: metrale-storage. Invariants:

• A non-zero driver status becomes an Err naming the call, except in the Drop impls, which ignore the status of the free or destroy call.
