/**
 * @file pwm_property_test.h
 * @brief Header for PWM property-based tests
 *
 * This file declares the PWM property test functions and registration.
 *
 * **Validates: Requirements 4.1-4.10**
 *
 * Property 4: PWM Subsystem Correctness
 * For any GPIO pin configured for PWM output (with frequency, duty cycle, resolution, and channel specifications), the PWM subsystem SHALL:
 * 1. Initialize based on YAML configuration
 * 2. Start and stop PWM output as requested
 * 3. Set and get duty cycle (0-100%) and frequency values accurately
 * 4. Validate parameters against hardware limits
 * 5. Handle hardware channel allocation and conflicts
 * 6. Maintain PWM state for runtime control and monitoring
 * 7. Deinitialize and free resources during shutdown
