1. Создай папку `bin` в корне проекта.
2. Напиши логику на Go, которая проверяет наличие `bin/sing-box.exe`.
3. Напиши функцию `runSingBox(configPath string)`, которая запускает `sing-box.exe` как скрытый фоновый процесс (`os/exec`).
4. Реализуй корректное завершение процесса (Kill) при нажатии кнопки "Отключить".
