Self-hosted AI companion

Runs the self-hosted companion cookbook in examples/cookbooks/self_hosted_companion/. It remembers a notes folder in the cognee dataset self_hosted_companion, then answers messages about it; each chat is saved to memory, so a later one knows it. Setup, the scripts and what each one does are in the cookbook's README.md.

Run every command from the repo root.

Steps

Without a notes folder of the user's own, or to see it work first, leave out <folder> below: the run then uses sample notes (the [setup] line says so). It needs only LLM_API_KEY. Tell the user the answer comes from sample notes.
