Function TestReconcileVolumes_DivergedIsIgnored

pkg/compose/reconcile_test.go:286–329

TestReconcileVolumes_DivergedIsIgnored verifies that a diverged volume produces no plan operations: recreation of diverged volumes is owned by ensureProjectVolumes (which prompts the user) and runs before reconcile, so the reconciler must not duplicate that decision.
