`veryfront/observability/otlp-setup`

*********************** OpenTelemetry OTLP Setup Thin wrapper that delegates to the ext-observability-opentelemetry extension via the TracingExporter contract. When the extension is not installed, all span operations silently no-op. Reads configuration from environment variables: - OTEL_TRACES_ENABLED: “true” to enable tracing - OTEL_SERVICE_NAME: Service name for traces - OTEL_EXPORTER_OTLP_ENDPOINT: OTLP endpoint - OTEL_EXPORTER_OTLP_HEADERS: Auth headers ************************
