dsh-official-skin: Apply an official website-quality skin to the DeepSeek Harness (DSH) interface

dsh-official-skin is an unofficial community plugin maintained by Klein, version 1.1.6, licensed under the MIT license. It focuses on Dark Mode, superimposing WebGL fluid aurora, GLSL particle whales, and constellation grids over a deep blue radial background. Light Mode features the blue hero gradient from the official homepage and frosted glass panels. The plugin preserves original interaction logic, keeping modals and functional panels opaque. It provides a one-click toggle in the top-right corner that follows DSH appearance settings with a 300ms cross-fade and actively releases the WebGL context upon reloading. It supports three installation methods: DSH Desktop, DSH Web, and dsh-market, is compatible with ^0.2.1-rc.5 || ^0.2.2-rc.1, requires WebGL2, and degrades to a pure CSS background if WebGL2 is unavailable.
