dsh-dance-plan: Dance Learning Plan

The dsh-dance-plan plugin for DeepSeek Harness (DSH) is built on the “everything is a plugin” philosophy and provides automated dance-learning planning for vertical-domain workflows. Maintained by uckkk, it is a pure Node implementation that runs without an internet connection. Users can install it via the terminal and invoke the `dance_plan` tool directly in conversations or scripts; after passing parameters, it returns a concrete dance-learning plan. The plugin code is open source and licensed under the MIT License.
