dsh-nothing-skin: A Nothing Phone–Style Skin

DeepSeek Harness (DSH) has added the `dsh-nothing-skin` plugin, which integrates the Nothing Phone design language into the DSH Web UI. The plugin features a dot matrix background, Space Grotesk typography, and a flat monochrome style with signal red as the only accent color. It supports light and dark modes, eight feature toggles, and custom wallpapers. The plugin can be installed via the command line or local file, then enabled and configured in Settings, with all settings persistently stored in a local directory.
