Crate klauthed_observability 

Observability for klauthed services: structured logging/tracing, Prometheus metrics, and OpenTelemetry trace export — from one TelemetryConfig.

init installs the global tracing subscriber (and, per feature + config, the metrics recorder and the OTLP trace pipeline) and returns a Telemetry handle. Keep it alive for the program’s lifetime; dropping it flushes OpenTelemetry spans.

use klauthed_observability::{init, TelemetryConfig};
use klauthed_core::config::Profile;

let config = TelemetryConfig::for_profile(&Profile::detect(), "billing-api");
let _telemetry = init(&config).expect("telemetry init");
tracing::info!("service starting");

Features:

• metrics — Prometheus recorder + a /metrics render handle.
• otel — OTLP trace export wired into the tracing subscriber.
