fix(installer): pause before closing in interactive mode

When double-clicked, the console window closes immediately after
installation finishes. Users never see the success/error message.
Add a 'Press Enter to close...' prompt in interactive mode so users
can read the output. Silent mode (-y, CI) exits immediately.
