Key changes: - Create SlowBlockTracer implementing BlockAwareOperationTracer - Move slow block logging and metrics collection into the tracer - Support tracer composition (wraps delegate tracer) - Centralize state access counters in EvmOperationCounters - Remove direct ExecutionStats management from AbstractBlockProcessor - Delete obsolete unit tests in favor of integration test The SlowBlockTracer is enabled via system property (threshold >= 0) and wraps the existing block import tracer. Future work will convert the system property to a CLI flag for better Besu integration.
