Aggregate Gmail Data to Create Google Calendar Events

## 2. Research Attendee + Company

API calls are made to the OpenAI Responses API using the new web search preview endpoint. This allows us to search the web for any mentions of each attendee. If the email address is a company email, we also make a search request to find out about the company. We use some context about ourself (in the "Set Context" node) so that the LLM can make an educated guess if there are many people with the same name.
