"""CLI frontend — the developer-facing driver of the harness.

Per v4.1 the CLI is a dev tool (Discord is the Phase 1 product frontend). It
assembles a real :class:`HarnessContext` via the :class:`ContextConcierge`
(OpenAI when ``OPENAI_API_KEY`` is set, else the offline FakeLLM) and runs one
turn through ``agent_loop`` — the harness's end-to-end smoke test.

Run:  python -m lang2sql.frontends.cli.app "your question"
