dsh-plugin-herdr: Managing Herdr Workspaces with DeepSeek Harness

dsh-plugin-herdr is a plugin designed for DeepSeek Harness (DSH) that aims to directly control the Herdr terminal workspace manager via Unix domain sockets. It provides 19 control-plane tools, supporting operations such as snapshots, panes, workspaces, and layout management, and implements a session-isolated UI. The plugin follows the MIT license, must be installed and enabled while the Herdr server is running, and becomes usable after restarting the configuration file.
