Reviewer's Guide by Sourcery

This PR removes Python 3.8 support from the project by updating type hints to use native syntax available in Python 3.9+ and modernizing dictionary operations. The changes primarily involve updating type annotations throughout the codebase and modifying dictionary merge operations to use the union operator.
