dsh-animation-studio: DeepSeek Harness Educational Video Production Workbench

The core philosophy of the `dsh-animation-studio` plugin for DeepSeek Harness (DSH) is “everything is a plugin,” aiming to enable models to generate instructional animations through instructions rather than code. The plugin encapsulates the animation workflow into 10 model-facing tools, allowing models to read and write a JSON-based `AnimationSpec` and use JSON Patch for atomic modifications and state rollback. The system records changes using an event-sourcing mechanism and supports asynchronous background rendering, interactive preview, and narration voiceover. Developers need to install Node.js, DSH, and the relevant dependencies, then add the plugin via the command line to enable the Agent to automatically complete the full animation production process from storyboard to rendering within a session.
