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

This script demonstrates the REAL Phase 4 orchestration:
- REAL Iterative Search (PubMed + ClinicalTrials + bioRxiv)
- REAL Evidence Evaluation (LLM Judge)
- REAL Orchestration Loop
- REAL Final Synthesis

NO MOCKS. REAL API CALLS.

Usage:
    uv run python examples/orchestrator_demo/run_agent.py "metformin cancer"
    uv run python examples/orchestrator_demo/run_agent.py "sildenafil heart failure" --iterations 5

Requires: OPENAI_API_KEY or ANTHROPIC_API_KEY
