dsh-mobile-hanui: Enabling DSH Web Interface for Optimal Mobile Usage

dsh-mobile-hanui is a DSH client plugin maintained by Z-6354. It automatically adjusts the web interface to a touch-screen layout when the viewport width is ≤ 1023px: the sidebar and detail panels switch to drawer and modal modes, pop-ups are centered full-screen, and a draggable floating menu button is provided. It also resolves issues such as the keyboard popping up automatically when switching sessions. The desktop experience remains unaffected. To install, run `pnpm add dsh-mobile-hanui` in `~/.dsh/profiles/web`, add the package name to the `dsh.profile.bundles` section in `package.json`, and restart dsh web.
