dsh-orca-glass: DeepSeek Harness Liquid Glass Refraction Layer

`dsh-orca-glass` is a playful skin-customization plugin designed for the web version of DeepSeek Harness. It injects SVG filters into the skin system via JavaScript to create a liquid-glass visual effect. The plugin uses `backdrop-filter` to produce chromatic dispersion, refraction, and frost effects, and supports enhancements such as grain, highlights, and floating cards. Installation requires the `orca-scene` skin, placing the plugin in `node_modules`, and registering it in `package.json`. Users can adjust parameters such as refraction strength and dispersion in real time through the console via `window.__orcaGlass`, and the settings are saved automatically.
