Pull Request Overview

This PR introduces a new system for generating policy data as JSON. Instead of parsing TypeScript source files at build time using tree-sitter, the system now exports policy definitions at runtime and uses the resulting JSON file as input for policy generation.

Key changes:

• Added a new --export-policy-data command-line flag that exports policy definitions to JSON
• Introduced new data types (PolicyCategory, LocalizedValue, ExportedPolicyDataDto) to standardize policy representation
• Refactored the policy generator to consume JSON instead of parsing TypeScript AST
• Updated all policy definitions to include required category and localization properties
