dsh-pure-chat: A Plugin That Makes DeepSeek Harness Agent Chat in Pure Text Mode Only

`dsh-pure-chat` is a DeepSeek Harness plugin designed to implement a pure text chat mode. By hiding global tools, intercepting execution, and modifying the system prompt, it ensures that the Agent only engages in text-based interactions and does not trigger filesystem or network requests. Users can dynamically enable or disable this mode for each session via the `/pure-chat` command. The plugin is maintained by community developers, is licensed under the MIT license, and runs on the `web` profile in the 0.1.x series.
