Function traceEnricher

traceEnricher(): Enricher
Creates a log enricher that attaches the active span's TraceId, SpanId, and TraceFlags to every log event.

Reads from the OpenTelemetry context via @opentelemetry/api, so it works with any tracer provider — including the one configured by import('../setupOtel.js').setupOtel.

No-op when no span is active.

Returns Enricher
an enricher that adds { TraceId, SpanId, TraceFlags } if a span is active
Example
```
import { createLogger, consoleSink } from '@cleverbrush/log';
import { traceEnricher } from '@cleverbrush/otel';

const logger = createLogger({
    sinks: [consoleSink()],
    enrichers: [traceEnricher()],
});
```
