Bug Fixes

• LLM Observability: Fixes incorrect span hierarchy in LLMObs traces when using the ddtrace SDK alongside OTel-based instrumentation (e.g. Strands Agents). OTel gen_ai spans (e.g. invoke_agent) were incorrectly appearing as siblings of their SDK parent span (e.g. call_agent) rather than being nested under it.

<!-- -->

• CI Visibility: This fix resolves an issue where pytest-xdist worker crashes (os._exit, SIGKILL, segfault) caused buffered test events to be lost. To enable eager flushing, set DD_TRACE_PARTIAL_FLUSH_MIN_SPANS=1.
