Artifact Manifest Writer

Artifact Manifest Writer（当天落盘版）

目录协议（强制）

• 输出：<MM_DD>/codex/artifact/manifest_<topic>.json
• deliverables[] 中的路径必须位于 <MM_DD>/ 下
• 若目标文件已存在：先给差异摘要，等待用户确认后再覆盖/更新

执行前先给 Plan（强制）

在写文件前，先输出 3 行以内的计划，让用户确认：

1. 收集 changes/commands/verification/deliverables
2. 填充 manifest schema 并校验路径
3. 写入 manifest_<topic>.json

Schema（必须字段；key 必须在）
