Confidence Score: 5/5

The dependency-only patch update appears safe to merge.

Summary

This PR consistently updates OpenTelemetry core, exporter, and hosting packages from 1.19.0 to 1.19.1 across central dependency management, the CloudShop example, and the Aspire starter template. Instrumentation packages remain at 1.19.0, whose dependency constraints permit the updated core version.

• Applies the patch update to all centrally managed OpenTelemetry core/exporter packages.
• Keeps the CloudShop example and generated Aspire starter dependencies aligned.
• No application logic, telemetry configuration, or security boundary is changed.
