DeepSeek Harness Plugin: V CYBER Cyber Theme (Multiple Color Palettes)

`dsh-v-theme` is a hacker/cyberpunk-style theme plugin for the DeepSeek Harness web client. It adopts a purely incremental design, offering seven hot-swappable styles (such as Cyber Neon and Tactical Panel), with baseline guarding and self-healing capabilities and zero side effects. The plugin supports persistent storage and requires a service restart after installation. Users can control plugin access and style switching via a master toggle in Settings; light mode automatically disables the theme.
