/**
 * Static regression coverage for #1784.
 *
 * Bun.spawnSync does not honor windowsHide on Windows (Bun 1.3.11), so
 * cold-start console-subsystem helpers must route through Node's
 * child_process APIs with windowsHide:true. These checks pin the spawn sites
 * that otherwise create focus-stealing conhost.exe windows.
