DeepSeek Harness Hello Kitty Suite: Themed Skins and Task Completion/Question Alerts

`deepseek-harness-hello-kitty-suite` is a client extension suite designed for the DeepSeek Harness (DSH) web interface, maintained by Angel2518975237 under the MIT license. It consists of two main components: First, the "Sweetheart Workbench Enhanced" Hello Kitty theme skin, which offers both light and dark modes, adding character decorations to the session header, sidebar, and chat area while preserving development semantic colors and supporting responsive layouts. Second, the task completion/question reminder plugin, which displays a pink card and plays a notification sound at the end of each conversation round. If the page is switched away, it sends a system notification (requiring authorization) and can detect whether the assistant's message ends with a question mark to remind the user to respond. For installation, first add the plugin repository using the `dsh plugin` command and
