feat: Add comprehensive Universal Docker Development Strategy with multi-language support

- Implemented a complete development environment using Docker, including a VS Code development container.
- Created a Dockerfile for a multi-language backend with support for Python, Node.js, Go, Java, and Rust.
- Developed a docker-compose file for a robust development stack including PostgreSQL, MySQL, Redis, MongoDB, Elasticsearch, and various admin interfaces.
- Added a setup script for automatic environment configuration and dependency installation.
- Documented the Universal Docker Development Strategy, detailing architecture, quick start instructions, available services, and troubleshooting tips.
- Established a Makefile for consistent command usage across different project types.
