Given a Rev 4 control or family:
For gaps action:
Show all controls that are new in Rev 5 (didn't exist in Rev 4):
If a specific family is provided, show only new controls in that family.
For withdrawn action:
Show all controls that were withdrawn in Rev 5:
For baseline-changes action:
Show what was added to and removed from a specific baseline:
For checklist action:
Generate a full transition checklist:
If no arguments provided, show the overview of changes and ask what the user wants to dive into.
