provision.sh step_cuda: NVIDIA's ubuntu2404 apt repository, cuda-nvrtc-dev-12-8, cuda-cudart-dev-12-8, cuda-driver-dev-12-8
(the libcuda stub) and opencl-c-headers; no nvcc (no build file calls it), no driver. tools/workers-remote.sh builds
igneum-worker-cuda and igneum-worker-opencl on the box from proto-cuda and proto-opencl with clang++ (static libstdc++),
prints sha256 and the glibc ceiling (2.38: fine for Ubuntu 24.04 hosts, not for 22.04 containers or HiveOS, where the Mac's
zig build stays). Proof: igneum-worker-cuda 1,613,992 B sha256 6db8a9ad..., igneum-worker-opencl 124,904 B sha256 0dea75bb...
remote-run.sh evaluates the command string in a subshell (a leaked set -e killed the runner after a successful build).
