     *
     * When enabled, a PinoLogRecordProcessor is registered as the global
     * OTel LoggerProvider. Log records emitted by OTel-instrumented libraries
     * (e.g. `@opentelemetry/instrumentation-openai`) will be written to the
     * NodeKit pino logger instead of being silently dropped.
     *
     * Each bridged log line contains all original OTel attributes plus
     * `otelScope`, `traceId` and `spanId` fields.
     *
     * Note: `otelScope`, `traceId` and `spanId` take precedence over any OTel
     * attributes with the same names.
     *
     * Note: when enabled, env-based OTel Logs configuration is ignored by the SDK
     * (OTEL_LOGS_EXPORTER, OTEL_EXPORTER_OTLP_LOGS_ENDPOINT, etc.) — explicit
     * processors take priority over env configuration.
     *
     * Note: must be enabled during NodeKit initialization, before any other code
     * registers an OpenTelemetry LoggerProvider — the global OTel provider can
     * only be set once per process.
