ci: Add GitHub Actions CI/CD pipeline

This commit adds a comprehensive CI/CD pipeline that includes:
- Multi-version Python testing (3.8-3.11)
- Code linting with flake8
- Code formatting checks with black
- Type checking with mypy
- Test execution with pytest and coverage
- Security scanning with bandit and safety
- Documentation building

The pipeline runs on pushes to main/develop and on pull requests.
