Add userspace GPIO test targeting the 8 pins exposed by the kernel GPIO capsule: Pin 0 => PA0 (ESP32 wakeup signal) Pin 1 => PA9 (peripheral power-down) Pin 2 => PB4 (general purpose) Pin 3 => PB5 (user LED) Pin 4 => PB10 (ESP32 enable) Pin 5 => PB13 (battery voltage monitor) Pin 6 => PB14 (charge indicator) Pin 7 => PC0 (ADC data ready) Tests: driver existence + pin count, walking output pulse, input reads, PA9 power pin validation. Requires the corresponding GPIO capsule in the tock kernel (jlab-sensing/tock ents-dev branch).
