connectMcuEdgesToService resubscribes its per-pin listeners whenever
pinNetMap changes. The subscription swept pin NUMBERS 0..63 and
reverse-mapped them to names ('GPIO2' on ESP32, 'GPIO17' on Pi) to match
against pinNetMap's keys — but those keys are the WIRE pin names ('2',
'4', 'A0'), so after the first solve the match failed for every pin and
the resubscription attached nothing. Any mid-run pinNetMap update then
silently killed the MCU-edge → SPICE path and the canvas froze at the
last solved state while the firmware kept toggling.
Masked until now because nothing perturbed pinNetMap mid-run on the
blink examples; pure ESP-IDF mode (#139) unmasked it — gpio_reset_pin()
leaves the internal pull-up enabled, the worker reports gpio_pull, the
handler requests an electrical resolve, pinNetMap gets a new identity,
and the ESP-IDF blink example's LED froze ON.
Fix: subscribe FROM the pinNetMap names, mapped to PinManager pins with
the same pinNameToArduinoPin the netlist collector uses (STM32 via
stm32PinNameToLinear), and hand schedulePin the netlist name so
handleMcuEdge's v_<board>_<pin> lookup hits the fast alterSource path
instead of a full rebuild per edge. The 0..63 sweep remains as the
pre-first-solve fallback. Also fixed pinNameToArduinoPin's dead 'GPIO'
branch ('GP' tested first turned 'GPIO32' into parseInt('IO32') = NaN).
