Module telemetry 

Agent-level observability — OpenTelemetry tracing, structured logging, Prometheus metrics.

Mirrors the wire crate’s telemetry layer but for agent lifecycle operations. Spans and structured logging go through the tracing facade and are always compiled (no-ops until a subscriber is installed). Prometheus metric definitions are gated behind the metrics feature.

TelemetryMiddleware

Auto-registered middleware that calls telemetry functions. Spans and log events are no-ops until a tracing subscriber is installed; metrics compile to no-ops without the metrics feature.
