Many async hook responses arriving at once now collapse into one batched transcript entry with per-event counts.

When multiple async_hook_response transcript attachments arrive together, they're now collapsed into a single async_hook_response_batch entry summarizing per-event counts, instead of appearing individually in the transcript.
