Jovie artists plugin package

Portable listing files for the ChatGPT plugin directory. The MCP server is https://jov.ie/api/chatgpt/mcp. It stays off until FEATURE_CHATGPT_APP_DIRECTORY_MCP=true is set in production and the app is redeployed.

Zip this directory so plugin.json is at the archive root, together with mcp.json, README.md, and assets/. Do not add a parent folder, secrets, reviewer passwords, or a demo recording URL.

Submission steps, the requirement map, and the production flag are in docs/integrations/chatgpt-app-directory.md. Do not upload this package from CI.
