+ * @brief FreeRTOS trace macros dispatcher
+ *
+ * This header provides a unified interface for FreeRTOS tracing.
+ * It dispatches to the appropriate implementation based on configuration:
+ *
+ * - CONFIG_ESP_TRACE_LIB_SEGGER_SYSVIEW: Uses SEGGER SystemView
+ * - CONFIG_ESP_TRACE_LIB_EXTERNAL: Uses external component's implementation
+ *   (external component must provide esp_trace_freertos_impl.h see components/esp_trace/README.md for more details)
