fix(server): ensure fatal startup logs are captured before exit

Replaces the asynchronous `log.severe` call in the main catch block with a direct, synchronous write to `stderr`, followed by `stderr.flush()`.

This fixes a race condition where the process could exit before the logger had a chance to write the fatal error message, ensuring that critical startup failure information is never lost.
