- BuiltinMindMapGenerator：从报告/残片/应用场景规则生成标准导图
- MindMapAiClient 接口 + RemoteAiMindMapClient 预留
- StandardMindMapService：生成/编辑/重新生成/回忆对比
- 对比算法：标题归一化 + Bigram Jaccard 模糊匹配
- ReviewController 新增 6 个端点
- MindMapTreeTool / MindMapNode / CompareResult 工具类
- 完整单元测试（10 个，全部通过）
- 更新 docs/review-module-design.md
