PR Summary

Low Risk
Low risk refactor that mainly changes how the pipeline is invoked (function wrapper + call site) without altering the underlying processing logic.

Overview
Moves the script’s main execution (the withCallingHandlers-wrapped pipeline) into a new, documented run_pipeline() function.

Reintroduces a small main guard (if (sys.nframe() == 0 || interactive())) that prints the banner and calls run_pipeline(), improving reusability while keeping the default CLI/interactive behavior.
