Разделение ответственности&#10;- **Core**: Бизнес-логика, не зависящая от UI&#10;- **UI**: Только код интерфейса и взаимодействия с пользователем&#10;- **System**: Специфичные для ОС функции&#10;- **Utils**: Переиспользуемые утилиты&#10;&#10;### 2. Минимальные зависимости&#10;- Core модули не зависят от UI&#10;- UI модули могут использовать Core&#10;- System модули изолированы и используются через интерфейсы&#10;&#10;### 3. Масштабируемость&#10;Структура позволяет легко добавлять новые компоненты без нарушения существующей архитектуры.&#10;&#10;## Сборка проекта&#10;&#10;Обновленный `CMakeLists.txt` автоматически находит все файлы в правильных папках и настраивает include пути.&#10;&#10;```bash&#10;mkdir build &amp;&amp; cd build&#10;cmake ..&#10;make&#10;```&#10;&#10;## Include директивы&#10;&#10;Благодаря настроенным include путям в CMake, файлы могут включать друг друга следующим образом:&#10;&#10;```cpp&#10;// Из UI модулей&#10;#include &quot;core/TimerState.h&quot;&#10;#include &quot;system/SystemTrayManager.h&quot;&#10;&#10;// Из Core модулей  &#10;#include &quot;TimerState.h&quot;  // внутри того же модуля&#10;&#10;// Из System модулей&#10;#include &quot;core/TimerState.h&quot;&#10;```&#10;&#10;## Будущие улучшения&#10;&#10;1. **Модульность**: Превратить компоненты в отдельные библиотеки&#10;2. **Тестирование**: Добавить unit тесты в папку `/tests/`&#10;3. **Плагины**: Создать систему плагинов в `/src/plugins/`&#10;4. **Локализация**: Добавить файлы переводов в `/resources/translations/`&#10;5. **Конфигурация**: Вынести конфиги в `/config/`" />
