agent: observability

When does this happen?

IF After upgrading Semantic Kernel to version >=1.49.0, Langfuse traces no longer include input/output messages because the OpenTelemetry conventions deprecated gen_ai.content.prompt and gen_ai.content.completion events.

How others solved it

THEN Upgrade Langfuse to version 3.66.0 or later, which includes support for the new OpenTelemetry event structure used by Semantic Kernel. This will restore proper ingestion of prompt and completion content into traces.
