Include Node REPL policy in turn metadata (#38241)

## What changed

- Parse `node_repl_auto_review_required` and `node_repl_disabled` from model catalog entries and include their values in each turn's Responses API metadata.
- Treat both fields as reserved metadata so client-provided values cannot override the selected model's policy.
- Use the selected review model's catalog entry when building metadata for review turns.

## Testing

- Cover metadata propagation across model switches, review turns, Responses API requests, and MCP tool calls.
