Fix repeat ownership and close out capture evidence

Start each repeat after its own manifest entry, refuse packets from a restarted
or stopped camera, keep a simulated repeat from reading as recorded evidence,
and decide completeness from the writer report. Add the operator summary (four
files plus an atomic pointer) and read-only video review of a hold window.

Verified with the full Autocal suite (567 passed), the shared recorder/playback
files (57 passed), the lint gate and the documentation gate; the two pre-existing
panel_check layout failures also fail on a clean HEAD worktree.

 # Autocal 录像复核与汇总实施计划
 
-状态：2026-10-16，待实施。范围：补齐录像可靠性、按事件回放和操作员汇总；不改变运动控制，不部署标定系数。详细字段见[数据契约提案](recording-summary-contract.zh.md)，DeepSeek 执行清单见[任务分工](recording-summary-tasks.zh.md)。本计划补充[原实施计划](implementation-plan.zh.md)，不把草稿描述当作功能验收。
+状态：2026-10-17 已实施，仅软件验证，待实机验收。范围不变：补齐录像可靠性、按事件回放和操作员汇总；不改变运动控制，不部署标定系数。实现落在 `frames_index.py`、`capture_guard.py`、`summary.py`、`summary_export.py`、`video_review.py` 与相应界面，详细字段见[数据契约](recording-summary-contract.zh.md)，执行与验证结果见[任务分工](recording-summary-tasks.zh.md)。本计划补充[原实施计划](implementation-plan.zh.md)，离线测试全绿不代表硬件验收。
