DSH Petdex Market: Pet Market and Desktop Companion in DSH Settings

The DSH plugin `nattocb/dsh-plugin-petdex-market` addresses the lack of visual feedback in Agent interactions by integrating a pet market into the DSH Settings interface. It provides a real-time catalog of approximately 4,500 pets, supporting browsing, installation, and native macOS desktop pet rendering. The pets can walk independently, be dragged, and respond to the Agent’s status (running while working and waving when finished). A same-origin proxy resolves WebView cross-origin issues, and configuration hot reloading is supported. Developed with Swift and AppKit, the plugin is macOS-only, easy to install, and becomes available in the settings interface after restarting the service.
