"""
Runner CLI pour ÈwéBench.

Usage:
    python run_benchmark.py --endpoint URL --model MODEL_NAME [--api-key KEY] [--verbose]
    python run_benchmark.py --preset deepseek [--verbose]
    python run_benchmark.py --preset local --endpoint http://localhost:8080/v1/chat/completions
    python run_benchmark.py --compare result1.json result2.json

Presets disponibles:
    deepseek  — DeepSeek API (nécessite DEEPSEEK_API_KEY dans .env)
    gemini    — Google Gemini (nécessite GEMINI_API_KEY dans .env)
    local     — Modèle local (ollama, vllm, etc.)
    custom    — API custom (nécessite --endpoint)
