Module telemetry 

Optional OpenTelemetry layer constructors for the engine’s tracing:: spans. Optional OpenTelemetry layer constructors for the engine’s tracing:: spans.

The engine emits tracing::debug_span! calls on every poll phase and on internal dispatch hot-paths regardless of feature flags. To export those spans to an OTLP collector, opt in to the tracing-otel feature and call otel::install_otlp_layer from your host crate’s startup.

The framework deliberately does NOT auto-install the subscriber

• the host owns the global tracing::dispatcher::set_global_default handle. Build the OTel layer here, then compose it with whatever other layers (fmt, json, etc.) your host uses.
