/**
 * @file driver.hpp
 * @brief GPIO driver interface - canonical types for MCU driver implementations
 * @ingroup hal
 *
 * This header provides everything a GPIO driver needs:
 * - GpioHandle: Pin reference with port, pin, and polarity
 * - PinMode: Pin configuration modes
 *
 * Drivers implement the following static interface:
 *   static void set_mode(const sbl::GpioHandle& handle, sbl::gpio::PinMode mode);
 *   static void write(const sbl::GpioHandle& handle, bool value);
 *   static bool read(const sbl::GpioHandle& handle);
 *   static void toggle(const sbl::GpioHandle& handle);
 *
 * Usage in driver:
 *   #include <sbl/hal/gpio/driver.hpp>
 *   using sbl::gpio::PinMode;
