Introduction to the DeepSeek Harness Plugin: dsh-workspace-groups

`dsh-workspace-groups` is a client plugin for DeepSeek Harness designed to address sidebar management clutter in multi-project scenarios. The plugin expands the sidebar view from a two-level hierarchy (projects and sessions) to a three-level hierarchy (categories → projects → sessions), supporting automatic categorization via YAML rules, fully manual grouping, drag-and-drop sorting, and persistent storage. It adopts a zero-intrusion design: manual operations only write to its own files, ensuring data security and reliability.
