Introducing the DeepSeek Harness Terminal UI Plugin

`xp266/dsh-tui` is an Ink-based terminal UI plugin for DeepSeek Harness (DSH), designed to transform DSH’s text-based interactions into a graphical interface. It supports streaming chat, collapsible tool cards, and high extensibility. Before use, the DSH CLI must be installed; it can be installed globally via the command line or enabled by adding it to the configuration file. This tool is suitable for developers who want to operate DeepSeek Harness through a TUI.
