Company brain: agent for follow-up

Runs the follow-up agent cookbook in examples/cookbooks/company_brain/follow_up_agent/. It remembers your Granola calls, Linear issues and Gmail inbox in the cognee dataset follow_up_agent, then works out the next steps of your latest call and posts them to Slack, or prints them. Setup, the scripts and what each one does are in the cookbook's README.md.

Run every command from the repo root.

Steps

With none of Granola, Linear and Gmail set up, the commands below run on sample calls, issues and email (the [setup] line says so), follow up a fictional call and never post to Slack; only LLM_API_KEY is needed. Tell the user the steps come from sample data. Add --sample to use the sample even when their accounts are set up.
