"""把一个 run 目录（如 runs_full/q0000）里**每个帖子**的 workflow.json，
与它对应的 post 信息（含 llm_evaluation）以及 query 词合并成一个 JSON。
以帖子为单位：一个 procedure 输出一个文件，文件落在 search_eval/workflows/ 下。
（例：q0000 有 3 个 procedure -> 写出 3 个 json）

映射逻辑：
  procedure 文件夹名形如  {FORM}_{platform}_{hash前缀}   例: A_gzh_8f5fbfb0
  -> 读 form_{FORM}.json，在 results[] 里找 case_id 以 "{platform}_{hash前缀}" 开头的那条
  -> 该 result 即对应的 post（post / comments / llm_evaluation / source_url ...）
  -> query / original_q 取自 form_{FORM}.json 顶层

输出文件名： {run_id}_{folder}.json    例: q0000_A_gzh_8f5fbfb0.json

本模块既是 build 脚本，也是一个 HTTP 接口：
  * build 函数（build_run / write_run）保留，供外部 import 调用或经 POST /build 触发；
  * 接口本身实时扫描 workflows/ 目录，把里面所有 json 以数组形式返回。

用法（build）：
  python build_workflows.py              # 默认处理 q0000
  python build_workflows.py q0003        # 处理指定 run
  python build_workflows.py --all        # 处理 runs_full 下所有 q* 目录

用法（接口）：
  python build_workflows.py serve [port] # 默认 8771
    GET  /workflows   -> 实时扫描 workflows/*.json，返回数组
    GET  /            -> 同上（方便直接访问）
    POST /build       -> body {"q":"q0003"} 或 {"all":true}，触发 build 后返回结果
