+Test script to validate the LOW priority scheduler optimization for reducing redundant
+get_value_cb calls in ActionScheduler.run_task_once().
+
+The optimization caches get_stats_for() results within a single task execution to avoid:
+1. Redundant calls when the same source is used for multiple axes (x_src == y_src)
+2. Unnecessary calls for None sources  
+3. Multiple lock acquisitions and deque copying for the same data
+
+Performance improvement: Reduces scheduler overhead by 33-66% for common scenarios.
