// electron-updater is CommonJS with a lazy getter for `autoUpdater`, so a named
// ESM import fails at runtime under Node ESM (cjs-module-lexer can't detect it).
// Use the default interop import and access the instance lazily inside initUpdater
// (after app.whenReady), matching the original intended evaluation timing.
