Лицензия, редактор, пульт и сборка

- Main: license service, IPC, router; закрытие окон; yauzl закрытие zip (EMFILE), zipRead тест
- Editor: стабильный projectState без мигания, логотип и меню, строки UI, LayoutShell overlay
- Control: ластик для всех типов эффектов, затухание/нарастание музыки при смене сцены
- Сборка: vite, build/dev scripts, obfuscate-main и build-env скрипты с тестами; package.json
