dsh-blender-pick: Blender Buying Guide Tool

In the DeepSeek Harness (DSH) ecosystem, the `dsh-blender-pick` plugin is maintained by uckkk and designed to address the lack of targeted tools when agents handle lifestyle decisions, such as choosing home appliances. It provides calculation logic for blender selection, enabling precise recommendations based on input parameters. As a pure Node implementation with no network dependencies, it can be installed and enabled via the official command, making it suitable for scenarios where an agent recommends or filters blenders. Users are advised to inspect the source code before installation. The license is MIT.
