Pull Request Overview

This PR consolidates the ModuleError and ModuleWarning classes by extracting their common logic into shared helper functions. The duplicate message creation and error details logic that existed in two separate files has been unified into a single file with reusable functions.

Key Changes:

• Extracted message creation logic into a shared createMessage function
• Extracted error details logic into a shared getErrorDetails function
• Merged both classes into a single file (ModuleError.ts) and removed the redundant ModuleWarning.ts file
