- 新增 GET /api/v1/admin/flow/timeline?sessionId=&limit=&before=：时间正序多轮，
每轮 {turnId,round,startedAt,endedAt,lanes[]}；limit 缺省 50/上限 200 + before 游标
- 数据源=落盘 flow_graphs + 内存最近一轮（同图 id 去重）；保留期 168h 外的轮次不返回，
但响应给 retentionHours/retentionEnabled/truncated ⇒ 前端如实标注，不悄悄少一块
- 老出口 GET /admin/flow/graph 零 diff；角色门 writeAuth（owner|admin）
- 4 个变异自检（游标 <= 重复、分组降级、去重缺失、truncated 静默）
