lbryany/dsh-herdr: DeepSeek Harness Herdr Status Integration Plugin

The `lbryany/dsh-herdr` plugin is used for DeepSeek Harness (DSH) status integration, aggregating root and sub-agent states into Herdr semantic states. It listens for events and maps DSH process states to Herdr states such as blocked, working, idle, or release-agent. The plugin communicates with Herdr preferably via Unix sockets, supporting persistent connections and session recovery. Installation requires a DSH and Node.js environment, making it suitable for developers who need to view DSH status in real time in the Herdr dashboard.
