/**
 * skill-case-get —— 案例采集 / 拆解 / 归档 主入口
 *
 * 管线：
 *   ① 输入识别：连续多图 / .docx / .pptx / 图文混合 / 裸图 / 视频
 *   ② 拆解提取：图片→skill-vision（OCR+语义）；docx/pptx→python3 标准库解包；视频→抽帧+skill-listen 转写
 *   ③ 分组与顺序：尺寸/时间/内容相似度判同组；九宫格按左上→右下给显式 order
 *   ④ 案例信息 vs 素材 分离
 *   ⑤ 合规判断：能否入库？客诉/负面？→ riskFlags / privacyFindings
 *   ⑥ 打标：静态属性 + 跟进状态七段 + 亮点/场景/异议 + 学校别名归一
 *   ⑦ 入库：caseSubmit 写待审清单（reviewStatus=pending, readyForUse=false），带幂等键
 *   ⑧ 字典自进化：新标签追加进 references/tag-dictionary.json
 *
 * 子命令：
 *   plan     只识别 + 提取 + 分组（不调任何模型，纯本机）
 *   ingest   plan + 图片理解 + 分类打标 → 产出 case-package.json（默认不提交）
 *   submit   读取 case-package.json（可先 reorder）→ 调云函数 caseSubmit
 *   reorder  调整 materialAssets 顺序（支持数组 + 顺序调整）
 *   dictionary  查看 / 追加标签字典
 *   selftest 本机自检（office 解包 + 分组 + 打标 + 合规）
 *
 * 安全：绝不打印 token/PII；生成的产物默认落在 <cwd>/case-get-outputs/。
