ChatGPT plugin package

The package uploaded to platform.openai.com/plugins to list Doop in the ChatGPT plugin directory. The server side (tool annotations, the preview card, OAuth discovery) lives in server/; this folder is only the listing: plugin.json (identity, listing copy, review test cases), mcp.json (points ChatGPT at https://doop.design/mcp with OAuth + dynamic client registration) and the logo.

Build the ZIP with node scripts/build-chatgpt-plugin.mjs (writes chatgpt-plugin/dist/doop.zip, gitignored). Before uploading, replace review.demo_recording_url with a reviewer-accessible video. Reviewer test credentials are entered in the dashboard (Metadata & Skills → Review information), never in this package. Process and field limits: .context/specs/chatgpt-app.md.
