dsh-client-ui-mobile: Mobile UI Optimizer for DeepSeek Harness Web GUI

DSH Mobile is a pure front-end plugin for DeepSeek Harness, designed to optimize the mobile experience. It converts the sidebar into drawer-style navigation, with top button or FAB entry support; adjusts the settings panel into a full-screen form, changes the details panel into a bottom form, and optimizes touch targets and safe areas. The plugin is upgrade-resistant, installed via ESM mode, and does not involve backend logic.
