Adds .cursor-plugin/plugin.json so this repo installs as a Cursor
plugin via /add-plugin shadcn-ui/ui.
- Loads the existing skills/shadcn/SKILL.md skill (auto-discovered
via the manifest's skills field).
- Registers the shadcn MCP server (npx shadcn@latest mcp) inline so
users get the same MCP config already documented for every other
client without hand-editing .cursor/mcp.json.
- Reuses skills/shadcn/assets/shadcn.png as the plugin logo.
No skill content or MCP changes — purely manifest wiring.
Made-with: Cursor
