"""End-to-end demo: an agent drives the capsule to the beacon and interacts.

Two agents:
  - ``llm`` (default): any tool-calling LLM via an OpenAI-compatible endpoint.
    Ships configured for a local ollama (http://localhost:11434/v1), swap
    ``--base-url``/``--model`` for any provider. The agent perceives through
    the protocol tools only; vision frames are summarized into a coarse color
    grid so text-only models can navigate too. The loop keeps a compact
    CURRENT STATE note (agent-side working memory, protocol §9) and nudges the
    model back on track if it drifts (no tool calls, moving away, collisions).
  - ``scripted``: deterministic sensor-driven fallback (same tools, no LLM).
  - ``auto`` (default): tries the LLM for a bounded number of steps, then
    hands off to the scripted agent so the demo always reaches the beacon.

Every tool call and result is printed to stdout as a transcript. The final
first-person frame is saved to ``--frame`` (default demo_final_frame.png).

Usage:
    python -m testbed.demo --agent llm --model gemma4:e2b
    python -m testbed.demo --agent scripted
