feat: enhance model version context with file metadata

- Rename `preview_overrides` to `version_context` to better reflect expanded purpose
- Add file_path and file_name fields to version serialization
- Update method names and parameter signatures for consistency
- Include file metadata from cache in version context building
- Maintain backward compatibility with existing preview URL functionality

The changes provide more comprehensive version information including file details while maintaining existing preview override behavior.
