Pull Request Overview

This PR fixes an issue where enums couldn't be used as injectable types in the dependency injection system. The fix adds logic to properly handle enums by ensuring they are not treated as collections during type resolution.

Key changes:

• Modified type checking logic to exclude class types (including enums) from collection handling
