Minor Changes

• #10004 b4d1373 Thanks @dario-piotrowicz! - add structuredWorkerdLogs option

  add a new top-level option named structuredWorkerdLogs that makes workerd print to stdout structured logs (stringified jsons of the following shape: { timestamp: number, level: string, message: string }) instead of printing logs to stdout and stderr

• #9556 8ba7736 Thanks @edmundhung! - Added a serviceName option to unsafeDirectSockets

  This allows registering the current worker in the dev registry under its own name, but routing to a different service.
