  /**
   * Default listener that logs process compilation failures.
   * <p>
   * This listener is primarily intended for development and testing. It logs compilation
   * failures at the DEBUG level, ensuring that these events do not create noise in
   * production logs by default. For production environments, it is recommended to
   * register a custom listener to route these events to a dedicated monitoring or
   * alerting system.
   * <p>
   * This listener respects the observability configuration switches and will be disabled
   * if observability is turned off.
