Update version to 2.0.3 and enhance version retrieval in CLI

- Bumped the project version to 2.0.3 in pyproject.toml.
- Refactored the version retrieval method in the CLI to use the __version__ attribute from the module, improving reliability and maintainability.
- Added import handling for compatibility with Python versions below 3.8.
