When a llama.cpp launch needs cmake/build-essential/git the user used to
get a four-distro dump ("apt: x / pacman: y / dnf: z / brew: w") and
had to pick the right one. Now:
- shell_routes /api/cookbook/packages probes /etc/os-release on the
target in the same SSH round-trip as the existing system-prereq
check, classifies into debian / arch / fedora / alpine / suse /
macos, and builds a single install_cmd_for_target string from the
(os_family, backend) matrix. CUDA hosts get nvidia-cuda-toolkit;
ROCm gets rocm-dev / rocm-hip-sdk; Vulkan gets libvulkan-dev /
vulkan-headers; etc.
- llama_cpp catalog entry gets system_prereqs: [cmake, g++, git].
When any of those are missing on the target, the row picks up
pkg.build_deps_missing + pkg.install_cmd_for_target for the
frontend to render.
- New POST /api/cookbook/install-system-deps endpoint runs the right
package manager via passwordless sudo on the target. Allowlisted to
{cmake, build-essential, g++, gcc, git, tmux, make}; sudo -n only
so it can never hang waiting for a password (returns a clear
"passwordless sudo unavailable" error via stderr instead).
