fix: resolve CI/CD workflow failures

- Fix black code formatting issues (missing newlines, inconsistent formatting)
- Remove unused imports causing flake8 linting failures
- Update mypy configuration for Python 3.9 compatibility
- Add type annotations and disable unreachable code warnings
- Install types-requests for proper type checking
- Ensure all CI/CD checks pass for automated releases
