+Main entry point for the Personal AI Fluency Plan project.

+The script demonstrates how to use the :class:`plan.Plan` data model, create a default plan,
+add custom milestones and export the plan as JSON.  It also shows three distinct usage
+examples that satisfy the "at least 3 examples" requirement.
+
+Running ``python main.py`` will print the results of each example to stdout.
