Abhinav b4507997e0 Use captured step settings when building model context (#44200) ...

## Why

Model changes during an active turn could leave context using the turn's initial model and settings, even after requests switched to the new model.

## What changed

- Build model, personality, approval, collaboration, app, plugin, and multi-agent instructions from captured step settings.
- Resolve multi-agent policy from the step's effective reasoning effort.
- Use the captured step's context window for full-context metadata and retain that step when rebuilding initial context for compaction.

## Testing

Add regression coverage for model switches updating context without duplicating updates, delegation policy following selected or model-default reasoning effort, and compaction preserving retained context after a model change.
