test(startup): isolate window persistence (#37)

- Issue #37: remove only the renderer's main-window resize persistence from the Windows package comparison.\n- Keep native startup geometry, the application code, and the delayed stability smoke unchanged so the result isolates the frontend persistence owner.\n\nRefs #37.
