"""查询分割统一入口（进程内函数版，无需启动任何本地服务）。

    from decompose import icl_decompose, unsupervised_decompose, supervised_decompose
    subs = icl_decompose("your question here")     # -> ['sub q1', 'sub q2', ...]

命令行：
    python decompose.py icl "Who directed the highest-grossing film of 1997?"
    python decompose.py supervised "..."
    python decompose.py unsupervised "..."

这是对 `qd_baselines` 包的薄封装：①监督式(本地 Llama+LoRA)、②无监督(本地 XLM)、
③ICL(gpt-4o-mini，可插拔)。所需环境变量见 .env.example。
④ SearChain 是检索反馈闭环，仍为服务版，见 使用说明.md 第 4 节。
