Выполнение шага 5:

• Updated Plan
  └ Продолжаю итерацию 5 как отдельный рабочий срез поверх текущих SSH credentials.
    □ Добавить модель/миграцию/repository для host_scans и покрыть repository тестами
    □ Добавить SSH command runner и LinuxHostScanner с whitelist read-only команд
    □ Подключить controller/routes/UI для запуска deep scan и просмотра результата
    □ Прогнать проверки и зафиксировать ограничения Docker-верификации
