/**
 * One-shot smoke: serialize a real OTLP/HTTP metrics payload through the
 * `createOtlpHttpMeterAdapter` exporter and POST it to the deployed
 * `deco-otel-ingest` `/v1/metrics`. Verifies the wire format end-to-end
 * (exporter → ingestor → ClickHouse) without standing up a Worker.
 *
 * Not part of the standard test suite — committed for repeatability.
 * Run with:
 *
 *   npx tsx scripts/smoke-otlp-meter.ts
 *
 * Expected output: `{"inserted":{"sum":1,"gauge":1,"histogram":1}}`.
