feat: implement toolbox-qadocker for Docker image auditing and QA

- Create specialized toolbox container for auditing Docker images and related files
- Include essential QA tools: Hadolint, Dive, ShellCheck, Trivy, Dockle, Docker client, Node.js
- Implement comprehensive build, run, release, and test scripts
- Add detailed documentation with usage examples
- Ensure all tools work correctly within the container
- Rename directory from toolbox-QADocker to toolbox-qadocker for consistency
- Update QWEN.md with comprehensive QA workflow using toolbox-qadocker
- Add mandatory pre-build audit process using QA tools
- Add validation process for testing from inside container environment
- Add comprehensive testing to verify all tools are working
- Optimize Dockerfile for best practices and security
- Ensure container runs as non-root user for security
- Add release script for versioned releases to registry
- Add test script to verify all tools are working correctly
