Invalid labels supplied through .Values.template.metadata.labels (or the
resourceMeta blocks) are not rejected by the API server: they live inside
the AutoscalingRunnerSet spec, whose CRD schema only enforces the value
type. The invalid value is only caught when the controller creates the
runner pod, at which point the EphemeralRunner is marked as failed with
ReasonInvalidPodFailure and the scale set never produces runners.
Validate every label and annotation map the charts render against the
Kubernetes key/value rules so helm install/upgrade fails immediately with
the offending values path, key and value.
Also render all metadata values as strings. Scalars such as 'true' or '1'
were previously emitted as YAML booleans and numbers, which Kubernetes
rejects for labels and annotations.
