dsh-biscuit-recipe: A Pure Node.js Biscuit Recipe Generator Plugin

The DeepSeek Harness plugin `dsh-biscuit-recipe` is maintained by uckkk and provides a hands-on baking solution implemented in pure Node.js. The plugin has no network dependencies, is lightweight, and offers low integration cost. Developers can install it via a command and invoke the `biscuit_recipe` tool to retrieve recipes. Note that the plugin runs with the current process's permissions, so it is recommended to review the source code before installation.
