"""Local-CDP battery orchestrator: tasks x arms x models x reps.

Resume-safe: completed cells in results.jsonl are skipped, so a killed
battery continues where it left off (same pattern as scripts/toolperf_abeval).

Usage:
    # start a headless Chrome first:
    #   google-chrome --headless=new --remote-debugging-port=9333 \
    #     --user-data-dir=/tmp/bubench-chrome --no-first-run --disable-gpu about:blank
    BUBENCH_BASE_TREE=... BUBENCH_PR_TREE=... BENCH_CDP_URL=http://127.0.0.1:9333 \
        python3 orchestrate.py [--tasks tasks/hard.json] [--models m1,m2] \
