fix(uart): el enganche de serie sobrevive a recrear el simulador 

El fan-out del Interconnect envuelve el onSerialData de la INSTANCIA y
la marca con un flag. Compilar, resetear o cambiar de motor crea una
instancia nueva: sin flag y sin envoltorio, asi que la placa dejaba de
oirse por el cable a mitad de sesion. Sintoma real: la Pi en modo Linux
encendia el LED del Arduino (Pi -> Uno), pero la respuesta del Arduino
no volvia nunca (Uno -> Pi), porque el Uno habia recreado su simulador
al compilar despues de que se construyeran las rutas.

Se vuelve a enganchar en cada simulatorMap.set (siete puntos: AVR,
RP2040, RISC-V, ESP32, STM32 y los shims).
