Pull Request Overview

This PR drops support for Python 3.7, 3.8, and 3.9, updating the minimum required Python version to 3.10. This enables the use of modern Python type hints and syntax throughout the codebase.

• Update minimum Python version from 3.7 to 3.10 across all packages
• Modernize type annotations to use built-in types instead of typing module equivalents
• Remove deprecated code and CLI options that were scheduled for removal in v2.0.0
