istio-0001: gateway reportGatewayStatus addressesToReport dedup O(I^2)
pilot/pkg/config/kube/gateway/conversion.go +
pilot/pkg/config/kube/agentgateway/gateway_status.go
Fix: map[string]struct{} seen-set replaces slices.Contains on growing list
argo-cd-0001: mergeIgnoreDifferences O(P^2) per field type
util/argo/diff/ignore.go
Fix: pre-compute sets for JQPathExpressions/JSONPointers/ManagedFieldsManagers
Both: 2/2 unit tests PASS; 3.4x and 3.7x speedup measured
