+Streaming search sends `{"type":"heartbeat"}` every 15 seconds without business events; use it only to keep the connection alive. Final `replace` payloads above 48 items are batched: the first event uses `type=replace`, later events use `type=append`, and every batch includes `replace_batch=true`, zero-based `batch_index`, `batch_count`, and final `total_items`. Collect all batches in order and replace the visible result atomically. After a `replace`, the final `done` event omits duplicate `items`.
