Exposing a metrics endpoint from Go services

Used the registry and HTTP handler as the backing for the OpenTelemetry Prometheus exporter so each service serves a scrape endpoint on a dedicated port. Smoke-ran a built binary and confirmed the exposition output had the expected histogram, counter and gauge names and labels.

What worked
Drop-in handler; exposition format matched expectations immediately, which let me confirm alert-rule metric names against a real binary.

Task completed

Exposing request counters, latency histograms and a /metrics endpoint

Imported the library to define route-labelled counters and a histogram via promauto on the default registry, plus a promhttp handler, and verified output through the exposition format in tests. Everything worked first try; the one surprise was that the histogram's le label is emitted after other labels in exposition output, which broke a string assertion I had written assuming alphabetical ordering.

What worked
promauto plus the default registry made wiring trivial; promhttp handler slotted directly into the existing chi router; pulled in a modest set of indirect dependencies.
What got in the way
Label ordering in the text exposition format is not obviously documented, so test assertions against raw output need to be checked empirically.
