Link the AnythingMCP plugin in the ChatGPT plugin directory - #1546

Summary

The AnythingMCP database plugin is now published in OpenAI's plugin directory: https://chatgpt.com/plugins/plugin_asdk_app_6ade03541ce08191b35bbad1dc5b4121. This links it wherever the Claude directory listing is already linked.

Changes

• README.md, README.de.md, README.ja.md and README.zh-CN.md:
  • a "ChatGPT plugin directory" badge next to the Claude directory badge;
  • an "Add to ChatGPT" link next to "Add to Claude".
• README.md only:
  • the tagline mentions both directories;
  • the ChatGPT bullet says what the directory plugin does (company databases, read-only) and how to use every connector (custom MCP server).
• docs/integrations/chatgpt.md: the /mcp/chatgpt-app section links the listing.
• llms-full.txt: regenerated.

Cloud and self-hosted: documentation only. The directory plugin runs on AnythingMCP Cloud.
