kycoming/dsh-product-design: Simplified Figma in Session Tab

The DSH plugin `kycoming/dsh-product-design` is a simplified version of Figma's product design canvas located within a session tab, maintained by KYCOMING and categorized as a client-side plugin. It offers a multi-artboard canvas with pan and zoom, 13 types of components, container nesting and grouping, snap alignment, constraints, and Auto Layout, component states, preview mode, and prototype interactions. It also supports exporting to PNG, single-file HTML, and React + Tailwind. Installation is performed via `dsh plugin --profile desktop/web add github:KYCOMING/dsh-product-design`; restart DSH after installation to enable it. The AI utilizes `/design` and `product_design_apply` to generate and modify designs, with results presented as thumbnail cards within the session. The plugin registers the `/dsh-product-design/api` route within the Host process, stores designs under `<DSH_HOME>/storages`, makes no external requests, and does not collect telemetry. It is compatible with DSH 0.2.2-rc.1 (tested) and has 0 stars.
