What

The SDK's control-protocol connection now keeps a new map, unansweredSettleHandlers, alongside its existing tracking of in-flight requests. It's used on the path that hands off a control_response for requests that are still pending when the process shuts down, passing them to the next process.

Why

This helps ensure that requests still awaiting a response don't lose their response handler when a process shuts down and control passes to the next one.
