When ADK_TELEMETRY_SCHEMA_VERSION_OPT_IN resolves to 2, replace the legacy
top-level 'invocation' span with an entrypoint 'invoke_workflow {entrypoint}'
span (entrypoint = root agent or root node name), set is_entrypoint, and emit
the gen_ai.invoke_workflow.duration metric alongside it. Entrypoint status is
tracked via a contextvar so nested/agent-as-tool workflows report
is_entrypoint=false and the span is not double-emitted when the ADK entrypoint
is itself a workflow. Schema v1 is unchanged.
