Add llms.txt file to improve AI development workflow

[PaulRBerg]

Summary

I recommend adding an llms.txt file to the Envio docs repository to improve the development experience when using AI coding assistants with Envio.

What is it

The llms.txt standard (https://llmstxt.org/) is a simple text file that provides structured, LLM-friendly documentation for developers using AI coding assistants. It acts as a condensed, machine-readable version of your documentation that helps AI tools understand your project better.

Example

You can see how we implemented this in the Sablier docs: sablier-labs/docs#348

Placement

Following the standard, the file should be placed at: https://docs.envio.dev/llms.txt

We do have a page with this: https://docs.envio.dev/docs/HyperIndex-LLM/hyperindex-complete

But I agree it would be nice to have it as a simple text. cc @DenhamPreen

llms.txt is a standard, it's more than simple text

Also helpful would be to get Envio listed in context7
