### What changes were proposed in this pull request? This PR aims to promote `KubernetesClientUtils` from `@Unstable` to `@Stable` API. ### Why are the changes needed? `KubernetesClientUtils` is a `@DeveloperApi` utility used by both Spark's internal K8s submission path and the Spark K8s Operator. It was introduced in Apache Spark 3.1.0 (SPARK-30985) and its public surface has remained stable for multiple releases. The most recent change was SPARK-53832 on 2025-10-08 (adding Java-friendly overloads), and there has been no breaking API change for roughly 6.5 months. Promoting it to `@Stable` signals this stability to downstream users like the Spark K8s Operator. ### Does this PR introduce _any_ user-facing change? No, this is an annotation-only change (API stability signaling). No behavior change. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling? Generated-by: Claude Opus 4.7 -- This is an automated message from the Apache Git Service.
