dsh-git-dashboard: DeepSeek Harness Dashboard for Out-of-Repo Read-Only Git Workspaces

`dsh-git-dashboard` is a Git dashboard plugin for DeepSeek Harness that displays branch information and workspace changes in the conversation header, helping developers intuitively understand code status. It supports file statistics, diff previews, branch comparisons, and opening local files. Installation requires a Node.js environment, and after configuring the dependency links, parameters such as timeouts and size limits can be adjusted via `cordis.patch.yml`. The plugin aims to optimize the DSH plugin ecosystem and is recommended for use in Loopback environments.
