- applyWindowsAppUserModelId() so Windows attributes toast notifications to the
app (kept in sync with build.appId via a test); no-op on macOS/Linux
- main window: setWindowOpenHandler denies uncontrolled popups, routes http(s)
links to the system browser; intentionally no will-navigate guard so dev HMR
reloads keep working
- preview view: denies popups + blocks non-http(s) navigation (file:/custom
schemes) while allowing in-page http(s) browsing
