Stand up the xtrain project skeleton: a Cargo workspace mirroring xserv's csrc/ + crates/ layout, with a single xtrain-cuda crate that wraps the CUDA Runtime over hand-written extern "C" FFI. build.rs compiles csrc/test/vecadd.cu via the cc crate targeting sm_120 (RTX 5090) and links cudart. A gated integration test runs the vector-add kernel on the GPU and asserts the result. When nvcc is absent (local GPU-less machine), build.rs skips CUDA compilation and sets a `no_cuda` cfg so host-side cargo check still works. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
