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.

+"""Diagnostic build: make the radio show what its SMS assembler actually sees.
+
+Three counters are surfaced on screen, so we can tell where reception stops:
+  RX  - data bursts handed to the assembler by the driver
+  HDR - data headers parsed (with the announced block count)
+  ASM - completed assemblies (all blocks collected)
+
+If RX stays at zero the bursts never reach the module and the problem is in the
+driver-side capture conditions. If RX counts up but HDR does not, header parsing is
+rejecting them. If HDR appears but ASM does not, blocks are being lost.
