Pull Request Overview

This pull request modularizes the policy generation script by extracting classes, interfaces, and rendering functions from a monolithic policyGenerator.ts file into separate, focused modules. The refactoring improves code organization, testability, and maintainability without changing functionality.

Key changes:

• Extracted policy classes (BooleanPolicy, NumberPolicy, StringPolicy, StringEnumPolicy, ObjectPolicy, BasePolicy) into individual files
• Moved type definitions and interfaces to types.ts
• Created a separate render.ts module for rendering functions
• Added comprehensive unit tests for the extracted modules
• Updated policyGenerator.ts to import from the new modules

This is awesome 🚀 Suggestion to add some tests that encode verbatim config generated with the old script

@joshspicer I added tests based on the new changes - there are some slight differences such as sort order etc and some updates due to the wrong type being used previously.

I've attached the diffs here in case they are interesting!
