Summary of Changes

Hello @abhishek-anand, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on preparing the project for an open-source release. It involves a comprehensive refactoring of file and directory names for improved clarity, the addition of standard open-source documentation, and a cleanup of configuration files to remove sensitive data and provide user-friendly templates. All internal references across the codebase have been updated to ensure consistency with these changes.

Highlights

• Project Restructuring and Renaming: Key directories and files have been renamed for clarity, such as cookbooks/ to examples/, mcp_main.py to server.py, and openai_testmcp.py to openai_client.py. This improves the project's overall organization and readability.
• Open Source Readiness: The project is being prepared for open-source release with the addition of essential files like LICENSE (MIT) and CONTRIBUTING.md. The .gitignore file has also been updated to exclude common development and personal configuration files.
• Configuration and Reference Updates: Personal information has been removed from config files, and a template (claude_desktop_config.example.json) has been added for easier setup. All internal references across Dockerfile, entrypoint.sh, and README.md have been updated to reflect the new file names, directory structure, and the new GitHub organization (BandarLabs).
• MCP Server Branding: The internal MCP server name has been updated from 'jupyter_tools' to 'CodeRunner', aligning with the project's new identity.
