DPH Task Board (@dph/taskboard): Adding a Status Dashboard to DeepSeek Harness Sessions

The DPH Task Board (@dph/taskboard) is a DeepSeek Harness community plugin designed to transform multi-session management into a visualized four-column status board (Todo, In Progress, In Review, Done). This plugin treats sessions as cards, supporting drag-and-drop categorization, attaching notes, priorities, and tags, along with search, JSON export for backup, and import functionality. It is deeply integrated into the Harness sidebar, allowing configuration of the model, reasoning intensity, and grouping when creating new sessions, and it displays the real-time running status of sessions via a "processing" breathing light. Data is primarily stored in the browser's localStorage, while the host side persists the board state to a local JSON file, enabling agents to directly read and analyze current work progress. The installation process requires a Node.js 18+ environment and goes through the deployment script.
