1. **Улучшил механизм консенсуса** – добавил динамическое членство и улучшил производительность в крейте `bounded-consensus` (эпохи конфигурации, методы `update_participants`).
2. **Реализовал продвинутый планировщик задач с временными ограничениями** – расширил структуры `Task` и `Assignment` в `distributed-planner`, добавил новые алгоритмы `DeadlineAwarePlanner` и `DependencyAwarePlanner`, обновил существующие алгоритмы для использования дедлайнов, приоритетов и зависимостей.
3. **Создал симулятор роя для тестирования** – новый крейт `swarm-simulator` с конфигурируемыми агентами, моделями сети, задержек и сбоев, а также демонстрационной функцией `run_demo`.
4. **Разработал графический интерфейс мониторинга** – веб-интерфейс на основе Warp (пример `web_monitor.rs`), отображающий состояние агентов, пиров и ключей CRDT в реальном времени.
5. **Интегрировал с ROS2** – создал крейт `ros2-adapter` для моста между ROS2 и SDK, дополнительно имеются готовые Python-примеры (`ros2_node_example.py`, `simple_robot.py`) для интеграции через Python-биндинги.

Все изменения сохранены в соответствующих файлах, обновлён корневой `Cargo.toml` (добавлены новые члены workspace), код соответствует стилю проекта и готов к использованию.
