"""本地跑需求生成：只写文件，不入库。

在项目根目录执行：

    .venv/bin/python examples/demand/run_local.py

默认：品类「早中晚好」，生成约 100 条。结果文件：

    examples/demand/result/早中晚好.json
    examples/demand/result/<execution_id>/execution_id_<execution_id>_demand_items.json

可选参数：

    .venv/bin/python examples/demand/run_local.py --cluster 早中晚好 --count 100
