The compile-time loop() override detection using decltype(&T::loop) fails when a component inherits from both Component (via PollingComponent) and BLEClientNode, as both define loop() methods making the expression ambiguous. Add a SFINAE-based has_loop_override<T> trait that gracefully handles this case: when decltype(&T::loop) is ill-formed due to ambiguity, it falls back to true (conservatively assuming a loop override exists).
