feat(firmware-info): копируй папку текущей сборки целиком

Добавь каталог назначения последним аргументом postcompile CCS и Keil. Копируй только архив текущего запуска с сохранением имени папки, всех файлов и проверкой SHA-256. Обнови MD-команды и проверки выбора папки, вложенных файлов и ошибок экспорта.
