Prepare a ChatGPT App submission

Use this skill as the Codex-facing guardrail around OpenAI Developers' official chatgpt-app-submission skill. The official skill understands the current chatgpt-app-submission.json schema; this wrapper makes sure it is run against the right repository, reviewed before upload, and never mistaken for a generic static plugin or a permission to submit.

For current platform terminology and availability, verify the official Plugins in ChatGPT and Codex guidance and Apps SDK documentation. OpenAI's current directory model packages new app submissions inside plugins.
