PSR-15 middleware that opens an OpenTelemetry Server span for each request. It is the span source of truth: it extracts the inbound trace context, starts and activates the span (so any actor ask/tell inside the handler links as a child), records http.* attributes and the response status, records handler exceptions, and always ends the span. All telemetry is fail-isolated — a telemetry error never breaks the request; the handler's own exception still propagates to the exception-handling middleware.
