DeepSeek Harness Project Group Plugin (dsh-ProjectModel)

The `dsh-ProjectModel` plugin is designed to address the context loss issue in DeepSeek Harness (DSH) native mode. It allows managing multiple project folders within a single session and enables cross-directory operations through “project groups.” Core features include organizing project groups, setting project descriptions to assist the AI in locating content, and providing tools for file read/write, command execution, and viewing AGENTS.md. The plugin specifies targets by folder ID and features secure sandbox restrictions and a zero-intrusion UI design, helping users conveniently perform cross-project comparisons and collaboration.
