DeepSeek Harness Plugin: dsh-plugin-codex-ui

`dsh-plugin-codex-ui` is a sidebar skin plugin for DeepSeek Harness, designed to provide a minimal Codex-style interface. It hides the global panel, restructures the browsing area into collapsible “Projects” and “Recents” lists, and simplifies creating a new session to directly clicking “New Conversation.” Users can click a project row to manage chat history, or hover over a recent session to archive it. The plugin requires Node.js 20 and pnpm, and a process restart is needed after installation for the changes to take effect. It is suitable for developers who prefer an efficient, focused experience for chat and project management.
