CUDA 13 убрал sm_61 (Pascal), CUDA 12.4 убрал sm_120 (Blackwell).
Sweet spot: CUDA 12.4 с PTX-only для sm_89, JIT compile на Blackwell.

CMAKE_CUDA_ARCHITECTURES=61-real;75-real;86-real;89-real;89-virtual
покрывает Pascal/Turing/Ampere/Ada native + PTX для forward JIT.

Ubuntu 22.04 jammy glibc 2.35 forward-compatible с host 24.04 noble.

.dockerignore исключает build/ (от хостовой cmake) — иначе
docker build падает с 'CMakeCache directory mismatch'.
