jif 4f1a2bb5ff Preserve fork runtime versions without loading full model context (#43545) ...

## Why

A fork cutoff can exclude the `TurnContext` that records the source's multi-agent runtime version. Recovering that version should not require loading the source's full model context.

## What changed

- Preserve `multi_agent_version` in fork session metadata before applying the cutoff. If absent, scan backward for the newest version-bearing `TurnContext`, respecting inherited segment boundaries and stopping once resolved.
- Load the latest model context for paginated forks only when approval or permission settings need to be restored.

## Testing

Add regression tests covering stored-version precedence, early termination without reading older segments, and version recovery within inherited segment cutoffs.
