Introduce a feature gate registry backed by k8s.io/component-base/featuregate so new capabilities can be gated behind --feature-gates=<Gate>=true|false with Alpha/Beta/GA lifecycle. Migrate the validation webhook toggle from the ENABLE_VALIDATION_WEBHOOK env var to a ValidationWebhook feature gate with backwards-compatible env var support.
Remove non-existent Helm values snippet from FeatureGates.md, add CLI-over-env-var precedence note to ValidationWebhook.md, and log effective gate states instead of just known feature names.

Use os.LookupEnv instead of checking for exact "true" so the deprecation warning fires whenever the env var is set.
