dsh-ui-tools: DeepSeek Harness Session Tool Call Tracing Plugin

`dsh-ui-tools` is a browser-side plugin for DeepSeek Harness, maintained by user liukj98, designed to address the challenge of intuitively viewing tool-call workflows in web interfaces. It registers a view in the session header to structurally display tool calls, parameters, results, and statuses. Operating as an information consumer, it does not interfere with model requests. Installation requires certain environment prerequisites and can be performed using the `dsh plugin` command. After installation, be aware of potential issues such as pnpm version restrictions and conflicts with built-in versions. It provides developers with a lightweight debugging entry point.
