fix(previews): bump to 0.1.1 so namespaceLabels actually ships

[nicacioliveira]

#6213 added namespaceLabels to the ApplicationSet template but bumped only the studio chart. release-sandbox-charts.yaml checks whether the version is already published and skips the push if so — correct behaviour, OCI tags should be immutable — so chart-deco-studio-previews:0.1.0 in the registry is still the build without it:

$ helm pull chart-deco-studio-previews --version 0.1.0
$ grep -c namespaceLabels templates/applicationset.yaml
0

Why it matters

chart-deco-studio 0.14.3 renders the preview Namespace itself, with preview.namespaceLabels supplying the label the Gateway admits routes by. If the ApplicationSet never passes that value, the namespace renders without the label and the HTTPRoute attaches to nothing — a 404 with a green Argo, which is precisely the failure #6213 exists to remove.

managedNamespaceMetadata still labels the namespace on the first sync, so this is not guaranteed to break — but it makes correctness depend on apply ordering between two writers of the same object, which is not something to rely on.

Rollout

Publishing 0.1.1 is not enough on its own: apps/studio-preview/values.yaml in decocms/deco-apps-cd pins chart-deco-studio-previews, and also still pins studioChart.version: "0.14.1" — two versions behind. Both need bumping there before any of this reaches a preview.

Summary by cubic

Publishes namespaceLabels by bumping chart-deco-studio-previews to 0.1.1 and fixes CI to render previews with those labels. Previously 0.1.0 omitted the field (immutable tag), so preview Namespaces lacked the gateway selector label and HTTPRoutes attached to nothing; now labels flow to chart-deco-studio 0.14.3 which renders the Namespace with the selector, removing reliance on managedNamespaceMetadata ordering. CI Helm template now sets preview.namespaceLabels so the namespace assertion validates a real render.

• Rollout
  • Update decocms/deco-apps-cd apps/studio-preview/values.yaml: set chart-deco-studio-previews.version: "0.1.1" and studioChart.version: "0.14.3".
  • After deploy, verify a preview Namespace has the gateway selector label and routes resolve.
