Paper Workflow: Dispatcher

This is the entry point, not a menu. A request such as 优化一下论文 or improve my manuscript names a goal, not a layer. Manuscript work happens at distinct layers, and editing the wrong layer first wastes the edit: a paragraph whose scientific role is wrong should never be polished, and a sentence whose claim is unstable should never be re-punctuated.

Do not answer a general manuscript request by loading a single specialist skill. Classify the request, then run the whole chain for that class.
