analytics stack. No Docker, no cloud account required.

- `tycoon data sources add/run/catalog` — register and ingest from any REST API,
  filesystem, or catalog source (GitHub, Slack, Stripe, HubSpot, Notion)
- `tycoon data analyze --rill` — auto-scaffold dbt staging models and Rill dashboards
- `tycoon start/stop` — manage Rill, Dagster, Nao, and DuckDB UI services
- `tycoon ask chat` — natural language queries via Nao (Ollama supported)
