Refactor MCP server and enhance development environment

This commit refactors the MCP server implementation, updates the Dockerfile with new development tools and dependencies, introduces a Makefile for building and running the application, and adds utility modules for sandbox management and Ollama integration. The server name has also been updated from 'echo-server' to 'PMO-Crazy-coder' in the configuration.
