Migrate from direct TraceQueueManager.add_trace_task calls to TelemetryFacade.emit with TelemetryEvent abstraction. This reduces CE code invasion by consolidating telemetry logic in core/telemetry/ with a single guard in ops_trace_manager.py.
- Add EnterpriseOtelTrace handler with span emission for workflows and nodes - Implement minimal-span strategy: slim spans + detailed companion logs - Add deterministic span/trace IDs for cross-workflow trace correlation - Add metric collection at 100% accuracy (counters & histograms) - Add event handlers for app lifecycle and feedback telemetry - Add cross-workflow trace linking with parent context propagation - Add OTEL exporter with configurable sampling and privacy controls - Wire enterprise telemetry into workflow execution pipeline - Add telemetry configuration in enterprise configs
