## What changed - Apply each server's `startup_timeout_sec` (or the default) while creating the MCP client, so the deadline also covers transport setup. - Launch local stdio servers on a blocking task so synchronous command resolution and process creation do not prevent the deadline from firing. - Recognize the new client-startup timeout error and show the existing `startup_timeout_sec` configuration hint. ## Testing - Extend the timeout error display test to cover the client-startup timeout.
