Demo: Full DeepCritical Agent Loop (Search + Judge + Orchestrator).

This script demonstrates Phase 4 functionality:
- Iterative Search (PubMed + Web)
- Evidence Evaluation (Judge Agent)
- Orchestration Loop
- Final Synthesis

Usage:
    # Run with Mock Judge (No API Key needed)
    uv run python examples/orchestrator_demo/run_agent.py "metformin cancer" --mock

    # Run with Real Judge (Requires OPENAI_API_KEY or ANTHROPIC_API_KEY)
    uv run python examples/orchestrator_demo/run_agent.py "metformin cancer"
