Dice Battle - DSH Web GUI Plugin

The DSH Web GUI provides a Dice Battle plugin that integrates six classic dice games, including liar's dice and red dot guessing. The plugin is open source under the MIT license, supports a single-player vs. AI mode and a bilingual interface in English and Chinese, while online multiplayer is not currently enabled. The game is launched from a sidebar entry and runs in a center-column iframe, using sandbox isolation technology to ensure security. Users can install it using the `dsh plugin` command; after installing and restarting, the casual game can be started from the sidebar.
