ChatGPT search and fetchers

OpenAI's OAI-SearchBot is used to surface websites in ChatGPT's search features, while ChatGPT-User visits a page when a user's question calls for it; because those visits are user-initiated, OpenAI says robots.txt rules may not apply to them. Blocking OAI-SearchBot in robots.txt governs appearance in ChatGPT search, not every fetch.
