Crate signinum_jpeg_cuda 

CUDA-facing device-output adapter for signinum-jpeg.

This crate intentionally exposes the same backend-selection surface as the Metal adapter. CPU requests return host-backed surfaces. Scalar auto requests stay on CPU, while full-tile batch auto requests may use nvJPEG when the CUDA runtime and library are available. Explicit CUDA requests return CUDA-backed surfaces or a clear unavailable error.
