Реализовать двухпанельный Commander от платформенного PoC до этапов P6-P20: EMM-каталог, сортировку и выбор, операции с файлами и деревьями, транзакционное копирование, метаданные, политику конфликтов и предварительную проверку свободного места. Добавить проектную документацию, HDD/MAME-сценарии и проверенные артефакты. Расширить libc операцией bank_write_page, исправлением режима O_RDONLY и связанными регрессионными проверками.
