A Major Version

It's been a long time coming, but time has come to draw the line in the sand. No alphas, no betas. Hope it finds you all well. Thanks to everyone who has contributed over the years.

This is a somewhat symbolic gesture, because semver-breaking changes are still hard to avoid with a large set of sub-1.0 dependencies we need to bump, as well as managing the large api surface of Kubernetes.

Therefore, the plan is to align our breaking changes and major bumps with Kubernetes versions / k8s-openapi versions for now, and this should allow our other releases to stream in. See #1688 for more information.

Kubernetes v1_33 support via k8s-openapi 0.25

Please upgrade k8s-openapi along with kube to avoid conflicts.

New minimum versions: MSRV 1.82.0, MK8SV: 1.30*

KubeSchema

The CELSchema alternate derive for JsonSchema has been renamed to KubeSchema to indicate the increased functionality.

In addition to being able to inject CEL rules for validations, it can now also inject x-kubernetes properties such as merge-strategy via #1750, handle #[validate] attributes #1749, and pass validation rules as string literals #1754 :

#[derive(CustomResource, Serialize, Deserialize, Debug, PartialEq, Clone, KubeSchema)]
#[kube(...properties)
struct DocumentSpec {
    /// New merge strategy support
    #[x_kube(merge_strategy = ListMerge::Set)]
    x_kubernetes_set: Vec<String>,
    /// CEL Validation now lives on x_kube and supports literal Rules:
    #[x_kube(validation = "!has(self.variantOne) || self.variantOne.int > 22")]
    complex_enum: ComplexEnum,
}

See kube.rs docs on validation for more info. Huge thanks to @Danil-Grigorev.
