Create workflow to auto-generate single LLM document

[rolznz]

Tools like https://gitingest.com/ allows us to generate a single document containing all the knowledge needed about the project for an LLM.

Then ask the agent to fetch e.g. fetch https://raw.githubusercontent.com/getAlby/js-sdk/refs/heads/master/llm.md to understand the Alby JS SDK

A workflow would ensure they are kept up to date.
