3//! Wire method: `nativeHost:getOSProperties` (cross-platform).
4//! Returns Electron-shaped `{ type, release, arch, platform, cpus }` tuple.
5//! Cached for the process lifetime - OS type, version, arch, and CPU topology
6//! are stable; spawning `sw_vers`/`uname` on every call wastes ~10 ms each.
