Use dsh-side-chat to open a side追问 session next to the DeepSeek Harness main session.

`dsh-side-chat` is a DeepSeek Harness Web plugin maintained by AHGGG: Select text in completed messages, and you can追问 in the independent right sidebar or send the annotated selection back to the main input box without switching the main session. The current npm package `@ahggg/dsh-side-chat@0.6.1` accurately corresponds to dsh 0.1.0-rc.6. Please refer to the community repository for the installation command. The sidebar shares the workspace with the main session, and closing the panel will not undo file changes.
