dsh-temp-chat: A DeepSeek Temporary Chat Widget on the DSH Page

`dsh-temp-chat` is a lightweight temporary chat plugin designed specifically for DeepSeek Harness (DSH). It provides a zero-configuration entry point for model interaction through a draggable “sprite” whale icon in the bottom-right corner of the page and a standalone chat window. The plugin can follow the default model of the DSH session or allow users to configure a custom endpoint. It includes supporting features such as streaming output, dark mode, message copying, and accidental-click prevention, while data is stored only in local memory and does not affect the main session history. It is ready to use after installation and restart, making it ideal for quick temporary interactions or testing within DSH pages.
