[BUG]: `namespace` missing from Helm Chart templates.

[kevin-kho]

Version

v0.4.0

Which installation method(s) does this occur on?

Source

Describe the bug.

When running helm template, against charts/topograph, the rendered manifests are missing metadata.namespace from namespace-scoped resources.

This does not affect topograph installations via Helm or ArgoCD where you can specify a destination namespace.

It does affect workflows where users are using kubectl diff to check changes against a specific resource, or kubectl apply to install topograph.
Omitting spec.metadata will default to the default namespace

I am using Helm v4.2.0

Minimum reproducible example

1. Clone repository
2. Run `helm template topograph charts/topograph --namespace topograph` > manifest.yaml
3. Reading `manifest.yaml` you will see namespaced scoped resources (such as ServiceAccount) missing `metadata.namespace`
    3a.`kubectl diff` will show the namespace-scoped resources will be applied to the `default` namespace.
