dsh-client-ui-girlfriend: Adds a WeChat-style AI girlfriend chat interface to DeepSeek Harness

dsh-client-ui-girlfriend is an MIT-licensed plugin for DeepSeek Harness (DSH), maintained by dalintian. It transforms the DSH Web interface into a WeChat-style role-playing chat platform, supporting multi-character management, AI portrait generation, and contextual interaction. Users need to configure four sets of OpenAI-compatible APIs for chat, vision, text-to-image, and text-to-video. The plugin provides complete role profile injection, context-based generation of photos or short videos, and image visual analysis functionality. Installation requires Node.js >= 22 and pnpm, and can be done via the `pnpm dsh plugin` command. The "girlfriend" configuration, independent of the native interface, is enabled by default (port 3081). Character data is stored in plain text.
