Add Conversation and Workspace Rollback to DeepSeek Harness with dsh-turn-rewind

DSH-Turn-Rewind is a DeepSeek Harness session plugin maintained by Anionex. It anchors workspace restore points based on user messages, allows rolling back files when the agent deviates from the intended workflow, and optionally restarts the conversation from that turn. This article verifies the installation command, two recovery modes, the security boundary of Change Ledger, and the limitation that version 0.1 only supports regular Git worktrees through the catalog page and GitHub.
