/**
 * hostinfo.ts — host fingerprinting.
 *
 * Compute backend + GPU device string come from node-llama-cpp's OWN report
 * (`llama.gpu`, `llama.getGpuDeviceNames()`) — the engine that actually
 * loaded the model, not inferred from `os.platform()`/`os.arch()`. Two
 * hosts can share a platform/arch and still land on different backends
 * (e.g. a Linux x64 box with no CUDA/Vulkan falls back to CPU) — this is
 * what turns shared results into a real model × infra matrix rather than a
 * model × OS-name one.
