Emits a root 'execution' span and one 'execution.status' child span per status history entry when an ExecutionNode reaches a terminal state. All span timestamps are derived from the existing status history so durations reflect actual time spent, not when this code ran. - New module: cloud_pipelines_backend/instrumentation/execution_tracing.py - Hook: metrics._handle_before_commit calls try_emit_execution_trace - Orchestrator: otel.setup_providers() so the exporter is active - Tests: InMemorySpanExporter-backed suite in tests/instrumentation/
