Charlie Marsh 05a93a8a1d Avoid cloning excluded turn items during thread resume (#46511 )

## Why

Resuming a running thread with a summary initial page cloned every active-turn item before discarding those outside the summary, including potentially large reasoning payloads.

## What changed

- Snapshot the active turn using the requested `TurnItemsView`, copying only the first user message and final agent message for summaries and no items for `NotLoaded`.
- Preserve full snapshots when the resume response includes full turns, even if its initial page requests a summary.
- Share item selection between snapshots and page responses, and skip selection when a turn already has the requested view.

## Testing

Add unit coverage for summary selection, completed-turn metadata, and metadata-only snapshots. Extend running-thread resume coverage for default summaries, explicit full pages, and full turns returned alongside a summary page.
