Pull request overview

Adds support for specifying per-internal-resource labels/annotations via new ResourceMeta fields on AutoscalingRunnerSet / AutoscalingListener / EphemeralRunner(Set) APIs, and wires that metadata into the controller’s resource builder (with accompanying CRD updates).

Changes:

• Introduce ResourceMeta API type and new spec fields to carry labels/annotations for internal resources.
• Apply the new metadata in ResourceBuilder when creating listener/runner internal resources.
• Regenerate/update CRDs (repo config + Helm chart packaged CRDs) and expand unit tests for propagation.
