Code review

Found 1 issue:

1. node_label_selector uses "karpenter.sh/nodepool=default" (no spaces around =), but every other pipeline in the repo uses "karpenter.sh/nodepool = default" (with spaces). Depending on how this value is parsed downstream, the missing spaces could cause the label selector to fail silently. At minimum it is an inconsistency worth aligning.
