/**
 * Datadog formatter — stdout JSON for collection by the Datadog Agent.
 *
 * Trace/span IDs are emitted verbatim from the `traceContext` getter (no
 * conversion). Datadog APM log-trace correlation expects Datadog-format IDs:
 * dd-trace-js already supplies these, so its IDs correlate as-is. 128-bit hex
 * IDs from an OpenTelemetry SDK may need matching formats on both sides — see
 * the README. If conversion is ever needed, it would ship as a separate
 * `datadog-otel` formatter (its own `LOG_FORMAT` value), leaving this one as-is.
