dsh-token-speed: Real-Time Speed Monitoring Plugin for DSH Clients

The DeepSeek Harness (DSH) plugin `dsh-token-speed` visualizes real-time inference speed using a circular dial. It offers real-time speed display, per-step precise calibration based on `usage.outputTokens` and `timing`, a details panel, status indicators, and a draggable memory feature. Built on a browser-side architecture, it does not modify host state and only reads conversation data through `uiConversation`, providing developers with a lightweight performance monitoring solution. Installation requires adding a local link dependency to `package.json` in the profile and running the installation command.
