@deepseek-ai/dsh-client-ui-muyu: A Draggable Cyber Wooden Fish

Users can accumulate merit by clicking the wooden fish, and it supports drag-to-move. Data is stored in the local browser's `localStorage`, so progress and position are preserved after a refresh. The component has no network access, no sound, and no sensitive operations, aiming to provide users with a simple interactive experience.
