Generate an AI-powered summary from a collection of highlights, data entries (notes), insights, themes, and/or tags. Provide one or more arrays of IDs and Dovetail will synthesize the content into a concise summary.

At least one of highlight_ids, note_ids, insight_ids, theme_ids, or tag_ids must contain at least one item. The note_ids field accepts data entry IDs (the product now calls these "data" rather than "notes").

Set with_citations to true (default) to include citation references in the summary. Each citation links back to the specific source item (highlight, data entry, insight, theme, or tag) that contributed to that part of the summary.

Returns a summary string and an array of citations with their source IDs and types.
