Drop support for Python 3.8 and 3.9, require Python 3.10+

This simplifies maintenance and allows using modern Python features:
- Updated pyproject.toml to require Python 3.10+
- Removed Python 3.8 and 3.9 from GitHub Actions workflows
- Reverted Python 3.8 compatibility changes (can use modern type hints)
- Updated classifiers to only include supported Python versions

This resolves workflow hanging issues on older Python versions.
