// Regression coverage for the systray2 runtime swap (port of upstream PR #1080).
// The bug upstream: the bundled Go binary in node_modules/systray2/traybin
// sometimes ships without the executable bit on macOS/Linux, causing the tray
// to spawn() with EACCES and the icon never to appear.
//
// We can't load the real native binary in unit tests, but we can verify the
// pure helpers that drive the swap: the package + version pin and the
// chmod helper's behavior on a synthetic binary tree.
