+            Enable monitoring of OpenThread tasks to detect if a task is blocked
+            and unable to continue its normal execution loop. Useful for debugging
+            issues where tasks stop progressing due to deadlocks or resource waits.

+            detected as blocked, ESP_SYSTEM_USE_EH_FRAME must be enabled in
+            ESP System Settings.

+            Set the timeout (in seconds) for detecting a blocked task.
+            The timer is started at the beginning of each task main loop
+            and stopped at the end. If the timer expires, the task is considered blocked.
