Describe the bug

When certain fields of LWS are not allowed to be modified, it is unreasonable that no error is reported after modifying these immutable fields under the RGB resource. In this case, how should I manage my detached resources? Is deleting and recreating them the only option? This seems to come with a relatively high cost.

Reproduction

reproduce step:

1. apply yaml https://github.com/sgl-project/awesome-sglang/blob/main/k8s/rbg/deepseekr1/rbg_dsr1.yaml wait it become ready

2. modify lws size and apply it , then observe whether the LWS replicas are rebuilt. The expectation is that the LWS replicas will be rebuilt, and the pods will also be rebuilt.
