- 保留每个提交的原日期，只重排时分秒到 21:00-23:00；同日严格递增， 间隔 5-40 分钟且秒位随机；窗口不足时自动压紧并在预览中标注 - 支持 --window/--since/--until、--interval（含 match-remote）、--seed、 --remote、--branch、--no-push - 安全措施：默认只预览（退出码 2）、脏工作区拒绝、改写前创建 refs/kopsc-backup/<分支>-<时间戳> 备份、推送前比对 tree 哈希、 只用 --force-with-lease - BuiltinRequest 增加 Confirmed，使内置命令能获知 CLI 已确认 --yes - 文档：新增 README.git.md，主 README 补充导航与示例
