docs(faq): add best practice FAQ about using await with scope disposal

- Added FAQ section in documentation (README and tutorials, EN + RU) recommending always using await when calling CherryPick.closeRootScope, scope.closeScope, or scope.dispose, even if no services implement Disposable.
- Clarifies future-proof resource management for all users.

+### Q: Do I need to use `await` with CherryPick.closeRootScope(), scope.closeScope(), or scope.dispose() if I have no Disposable services?
+
+**A:**  
+Yes! Even if none of your services currently implement `Disposable`, always use `await` when closing scopes. If you later add resource cleanup (by implementing `dispose()`), CherryPick will handle it automatically without you needing to change your scope cleanup code. This ensures resource management is future-proof, robust, and covers all application scenarios.

+### В: Нужно ли использовать `await` для CherryPick.closeRootScope(), scope.closeScope() или scope.dispose(), если ни один сервис не реализует Disposable?
+
+**О:**  
+Да! Даже если в данный момент ни один сервис не реализует Disposable, всегда используйте `await` при закрытии скоупа. Если в будущем потребуется добавить освобождение ресурсов через dispose, CherryPick вызовет его автоматически без изменения завершения работы ваших скоупов. Такой подход делает управление ресурсами устойчивым и безопасным для любых изменений архитектуры.
