Env vars & config

In almost every case you don't need to set any of these — the defaults target the production ToolCairn API and sensible logging. Override only when you're building against a local engine or debugging.

Override the API endpoint. Defaults to https://api.neurynae.com. Point at a dev instance for local testing.
