feat: add centralized build validation command and refactor port configuration

- Introduced a new command for validating project builds, providing detailed instructions for running builds and intelligently fixing failures based on recent changes.
- Refactored port configuration by centralizing it in the @automaker/types package for improved maintainability and backward compatibility.
- Updated imports in various modules to reflect the new centralized port configuration, ensuring consistent usage across the application.
