Overview

Query: Aggregate swallowed exception data across hourly buckets for dashboard display.

Groups by (exception_class, raise_location) and sums raise/rescue counts across all rescue_locations and time buckets. This is important because the tracker stores raise events (rescue_location=nil) and rescue events (rescue_location set) in separate rows — grouping by rescue_location too would prevent the ratio from ever being computed. Filters to entries with rescue_ratio >= threshold (i.e., likely swallowed). Returns array of hashes sorted by total rescue count descending.
