- Switched intstr.Type to sized integer to follow API guidelines and improve compatibility with proto libraries ([#83956](https://github.com/kubernetes/kubernetes/pull/83956), [@liggitt](https://github.com/liggitt))

- Added the feature gates `StrictCostEnforcementForVAP` and `StrictCostEnforcementForWebhooks` to enforce the strict cost calculation for CEL extended libraries. It is strongly recommended to turn on the feature gates as early as possible.
