undo

DSH plugin: snapshot & rollback your plugin/skin/settings configs. Auto-save on change, undo/redo stack, snapshot manager panel, keyboard shortcuts, plus an offline PowerShell CLI & GUI that work even when DSH won't boot.

Claude Code /rewind for DeepSeek Harness — git-first workspace snapshots before every mutation, turn-boundary session forks, one-shot /rewind restore. A dsh-plugin capability seam.
