create llms.txt and llms-full.txt for LLM to understand Cube docs

Hi, can cube.js team create llms.txt and llms-full.txt? These two files are basically special versions of development documents.

These formats are designed to be more compatible with large language models and can significantly enhance the understanding of Cube.js for AI coding assistants like Cursor and Claude. This would greatly assist developers in using these tools to accelerate their development with Cube.js.

Given the growing popularity of AI coding assistants and the fact that many open-source projects are now offering these formats, I believe this feature would be highly beneficial for the Cube.js community.
