Pull Request Overview

This PR improves error handling when loading Python config modules and updates VSCode extension tests to assert the new error messaging.

• Wraps the Python module import in loader.py in a try/except to raise a descriptive ConfigError on import failures
• Refactors an existing test to use an explicit expect assertion and adds a new test for invalid config.py in the sushi example
