Pull request overview

This PR adds support for custom pod-level annotations and labels on the Helm chart's Deployment template, allowing users to attach metadata (e.g., Prometheus scrape configs, Istio sidecar injection, Datadog tags) to pods without modifying the chart directly.

Changes:

• Added podAnnotations and podLabels values (defaulting to empty maps) in values.yaml
• Updated deployment.yaml template to conditionally render pod annotations and merge custom pod labels alongside the existing app label

[Copilot]

The podAnnotations and podLabels values are missing descriptive comments, which is inconsistent with the rest of this file where every value has a # comment explaining its purpose (e.g., # replicaCount is the number of replicas for the deployment on line 13, # resources is the configuration for resource requests and limits on line 20). Please add comments like # podAnnotations are additional annotations to add to the pod template and # podLabels are additional labels to add to the pod template.

Suggested change

	podAnnotations: {}
	# podAnnotations are additional annotations to add to the pod template
	podAnnotations: {}
	# podLabels are additional labels to add to the pod template
