Enhance MCP tool functionality and improve logging capabilities

- Introduced new MCP tools for executing Luau code, inserting models, and retrieving console output, enhancing the plugin's capabilities for user interaction.
- Implemented a logging system to capture console output and provide detailed feedback during code execution and play mode operations.
- Updated the MCP stream to handle passthrough commands, allowing for better integration of tool commands and improved error handling.
- Enhanced the TODO list to reflect new tasks related to documentation for the added MCP tools and logging features.

These changes aim to improve the overall functionality and user experience of the MCP integration, particularly in script execution and model management.
