Add GitHub Actions CI/CD pipeline

Implement automated testing and quality checks for pull requests and
main branch pushes. The pipeline includes:

- Dependency installation with uv
- Security vulnerability scanning with uv-secure
- Code linting with ruff
- Code formatting verification with ruff
- Test execution with pytest
- Coverage reporting

All checks must pass before code can be merged, ensuring consistent quality standards.
