cassirer-openai d4b19eca27 Preserve agent message deliveries in rollout traces (#60673) ...

## Why

An accepted agent message may never appear in a later inference request or compaction snapshot. Rollout traces need to retain the delivery and its interaction edge even when the receiving agent makes no further request.

## What changed

Capture agent message payloads in `HistoryItemAccepted` events and create conversation items when those receipts are replayed. Reuse each item's ID when it later appears in a request or checkpoint, updating its body to the model-visible representation. Repeated receipts preserve that representation without duplicating the item.

## Testing

Extend the spawn-edge regression test to cover delivery before any child inference, stable item IDs across a later request, and preservation of trimmed content after a repeated receipt.
