Shortened summaries in API reference

Editor assessment

The subject states the change exactly: summaries in the API reference were shortened. Direction, target, and effect are all present, and a reader needs no diff to picture the edit. Docs is right and no scope is needed for the reference site. No body appears; for a formatting pass across generated summaries the headline is complete, though the trimming criterion (length limit? clarity?) would have been a welcome line. Imperative-adjacent, clean, compact. A fully adequate one-liner.
