DMR-данные (SMS) на TYT MD-UV380 под OpenGD77

Восстановлено из транскрипта сессии после потери рабочего дерева на сервере сборки.

Что внутри:
- четыре новых модуля прошивки (приём, сборка исходящего, меню Messages);
- правки существующих файлов в виде скриптов, с порядком применения;
- инструменты стенда: снятие экрана рации по USB, дамп кадров, эталонная сборка пакета;
- NOTES.md: что проверено в эфире, что не доделано, где грабли.

Работало в эфире в августе 2026: данные ходят в обе стороны в режиме хотспота,
рация принимает SMS и показывает на экране. Отправка собрана и сверена с эталоном
сервера побайтово, но в эфире не проверялась.
