dsh-frontend-inspector: A Frontend Source Code Locator Tool for DeepSeek Harness

The `dsh-frontend-inspector` plugin maintained by Lovstudio solves the challenge of debugging DeepSeek Harness production build artifacts. By leveraging Host extension points and the Lovinsp toolchain, it maps runtime DOM elements back to their source code locations. The plugin supports two modes: Source Checkout mode, which requires a local build and enables precise navigation to the editor; and npx mode, which requires no checkout, labels the plugin source only, and navigates to GitHub on click. After installation, users can hold the shortcut key and click an element to use it, making it suitable for development scenarios that require quickly locating the source code of UI components.
