dsh-canvas-flow: Build Your Workflow on a Canvas

`dsh-canvas-flow` is an open-source plugin for DeepSeek Harness. It uses an infinite canvas and connection mechanism to link tasks, intuitively showing data flow. It supports three card types: Text (document generation), Design (design mockup generation), and App (code generation), with multi-format export and secondary modifications. Users can install it in the client and drag cards to build workflows, enabling continuous iterative delivery from requirements to code.
