DeepSeek Harness Plugin: dsh-plugin-multi-root-workspace

The `dsh-plugin-multi-root-workspace` plugin, maintained by cherrchen, is designed to address the complexity of frequent directory switching required by DSH Agent when working with multi-Git-repository projects. It extends the writable scope of the Workspace to “one primary root + N additional roots,” allowing the Agent to read and write directly without learning new tools. Core features include a zero learning curve (leveraging native tools), no security downgrade (based on kernel sandboxing), multi-version compatibility, and management via a CLI command (`/workspace-folders`) and a sidebar GUI panel. Installation requires enabling builds to handle the native dependency `koffi`, and version compatibility should be observed. Features are limited on the Windows platform, and configuration errors will trigger immediate error reports.
