RT-4D: реверс прошивки, русификация, кастомный UI, флешеры

- Полный RE стока V3.25 (Cortex-M4F) + FM100B: карта памяти, протокол, codeplug, UI-архитектура
- Русификация: свой CP1251-шрифт + патч рендера, перевод меню и надписей, ребренд Ru-4D V3.25
- Блюпринт переделки UI + C-тулчейн (clang thumbv7em), доказан инъекцией
- Готовые флешеры: WebSerial .html и Windows .exe со вшитой прошивкой
- Дамп SPI рации, стоковая прошивка, инструменты сборки
