dpskh/dsh-checkpoint

安装

## Working together

The marker only earns its keep with a fold: mount both plugins so `rewind` can collapse the exploration the marker anchors. `checkpoint` alone records inert markers; `rewind` alone has nothing to fold and fails with a no-checkpoint error.

把 dpskh/dsh-checkpoint 加入你的 DSH 配置（web profile）即可启用。
