Walkthrough

Introduces an openshift-tests Go sub-module containing Ginkgo e2e tests for the VSphereMixedNodeEnv feature gate and a Cobra-based vmware-vsphere-csi-driver-operator-tests-ext entrypoint binary. The Makefile gains build-tests-ext and vendor targets; the Dockerfile compresses the tests-ext artifact and includes it in the final image.

Changes

OpenShift Tests Extension

Layer / File(s)	Summary
openshift-tests sub-module declaration openshift-tests/go.mod	Declares the openshift-tests module at Go 1.25.0, pinning direct dependencies on Ginkgo/Gomega, OpenShift test extension, OpenShift API/client/library-go, Cobra, and Kubernetes libraries; adds replace directive for the OpenShift ginkgo fork.
Makefile targets and Dockerfile packaging Makefile, Dockerfile.openshift	Extends all target to depend on build-tests-ext; adds build-tests-ext and vendor phony targets; extends clean; Dockerfile builder stage gzips the tests-ext artifact and the final image copies both the operator binary and the .gz file.
E2E test helper functions openshift-tests/e2e/doc.go, openshift-tests/e2e/hybrid_environment.go	Adds package doc, timeout/interval constants, and five helper functions: categorizeNodesByPlatform, isHybridEnvironment, verifyClusterCSIDriverState, updateClusterCSIDriverState, and waitForOperatorHealth.
VSphereMixedNodeEnv Ginkgo test specs openshift-tests/e2e/hybrid_environment.go	Adds the Describe block with BeforeEach/AfterEach client wiring; one It validates ClusterCSIDriver management state for all-vSphere vs hybrid clusters; one serial It forces Managed state in a hybrid cluster, asserts degradation/non-upgradeable conditions, then restores state via defer.
Tests-ext entrypoint and extension registry openshift-tests/cmd/vmware-vsphere-csi-driver-operator-tests-ext/main.go	Wires logging, flag normalization, extension registry with parallel and serial suites, builds Ginkgo specs, scans spec names for [platform:X] markers to add PlatformEquals includes, registers specs, and executes the Cobra root command.

I'll need to run the techpreview serial to validate the serial test.
