dsh-aspect-ratio: Frame Aspect Ratio Calculator

dsh-aspect-ratio is a local aspect-ratio calculation plugin designed specifically for DeepSeek Harness (DSH). Maintained by uckkk and implemented in pure Node.js, it can be invoked in DSH sessions without network requests. Users need to install it using a specific command and add the plugin name to the `dsh.profile.bundles` field in `package.json` to enable it. It is suitable for scenarios such as video generation that require local aspect-ratio calculation, but execution requires attention to permissions and source code review.
