List Buyback Accelerations

Get market-wide buyback acceleration events.

Returns companies whose buyback execution pace jumped significantly (>=10pp completion between consecutive monthly reports). Completion is recomputed from cumulative vs authorized shares, and only rows that pass the same validity gate as /buybacks/analysis are considered, so an acceleration reflects real execution rather than a parse artifact.
