Benjamin Carlsson e6ff749506 Render completed assistant messages directly during replay (#42325) ...

## Why

Buffered thread snapshots can contain both streaming deltas and the completed
assistant item. Replaying both reconstructs an already-finished stream instead
of restoring its finalized transcript entry.

## What changed

- Omit superseded assistant deltas from replay snapshots when a matching
  completed item follows them.
- Preserve unfinished or unrelated deltas and treat other events as replay
  barriers so text needed before tools or prompts is not dropped.
- Render completed replay items directly as formatted history cells while
  preserving message order, separators, and composer drafts.

## Testing

Added replay tests covering completed, unfinished, unrelated, and
barrier-separated deltas, plus deterministic Markdown rendering and draft
preservation.
