`OAI-SearchBot`

OpenAI says OAI-SearchBot is used to surface sites in ChatGPT search. Sites that opt out are not shown in ChatGPT search answers, though they can still appear as navigational links. OpenAI says this setting is independent of GPTBot, and that a robots.txt change can take about 24 hours to affect search.
