/**
 * Regression test for the MCU-edge listener pin-name mismatch.
 *
 * connectMcuEdgesToService subscribes its per-pin listeners from the
 * netlist's pinNetMap, whose keys are the WIRE pin names ('2', 'A0',
 * 'GP4'…). It must map those names to PinManager pin numbers with the
 * SAME function the netlist collector (collectPinStates) uses. The old
 * code reverse-mapped pin NUMBERS to names instead — producing 'GPIO2'
 * on ESP32, which never matched the wire's '2' — so any mid-run
 * resubscription (triggered e.g. by the gpio_pull that pure ESP-IDF's
 * gpio_reset_pin reports) silently detached every listener and froze
 * LEDs while the firmware kept toggling the pin.
