// test_radio_mesh.c — интеграционный тест рации: дедупликация дублей в mesh (diamond).
//
// Однопоточный: 4 узла (A, B, D, C) в одном процессе, один UASYNC, без fork.
// Топология — diamond: A↔B, A↔D, B↔C, D↔C (A сервер, B и D — клиенты к A +
// серверы, C — клиент к B и к D). Все четыре в одной CHAT-группе.
// Master state-machine на таймере.
//
// Сценарий:
// 1. A,B,D,C radio_on → флаг TOPO_FLAG_RADIO распространяется по BGP.
// 2. A: radio_talk_begin + N кадров + radio_talk_end.
// Кадр идёт к C двумя путями (A→B→C и A→D→C) — дубль гасится кэшем
// (src,stream,seq) в radio_recv.
// 3. Проверка: B, D, C получают ровно N кадров (без дублей), порядок seq
// и FIN корректны; у C счётчик дропнутых дублей > 0 (путь дедупликации
// реально отработал).
