rhan-oai 800d183e2d Use captured step settings when spawning subagents (#46075) ...

## Why

After a settings update during an active turn, spawned agents could inherit the turn's initial model and reasoning settings. Effort-only overrides could also be validated against the wrong model.

## What changed

Build child configuration from the invoking step's captured model, effective reasoning effort, and reasoning summary in both multi-agent versions. Validate effort-only overrides against that captured model's supported reasoning levels.

## Testing

Add regression coverage for spawning after an active-turn settings update in both multi-agent versions, including effort-only overrides. Update configuration tests to check captured settings and the model's default reasoning effort.
