dsh-plugin-mobile-touch: DeepSeek Harness Mobile and iPad Touch Optimization Plugin

`dsh-plugin-mobile-touch` is a plugin specifically designed to address interaction issues with DeepSeek Harness (DSH) on iPads and mobile devices. By rewriting touch logic, it optimizes swipe responsiveness in the session list, prevents accidental soft keyboard pop-ups, and locks the iPad sidebar in its expanded state. The plugin features smart hardware awareness, activates only on touch-enabled devices, and provides precise scrollbar rendering with fully adaptive responsiveness. Installation supports npm and one-click CLI mounting, and requires DeepSeek Cordis version 3.0.0 or higher.
