GenAI/MCP bench CLI (uhbs genai-bench)

Experimental. Replay-first (CI-safe). Does not change UHQS. Not MCP-exposed.

pip install 'uhbs[genai-bench]'
uhbs genai-bench example beginner --out genai-beginner
uhbs genai-bench analyze genai-beginner/replay.json --out genai-benchmark-report.json
uhbs genai-bench stub --out replay.json   # write deterministic stub

Live decoy probing requires uhbs[lab] and explicit experimental flags; keep sandboxed.
