🐛 Bug Description

Seems environment variable KAGENT_URL is set by default.

It looks like this KAGENT_URL is set as "http://kagent-controller.kagent:8083" by default which is hardcoded.

Which is weird that the helm chart explains like this

controller:
  replicas: 1
  loglevel: "info"
  # -- The base URL of the A2A Server endpoint, as advertised to clients.
  # @default -- `http://<fullname>-controller.<namespace>.svc.cluster.local:<port>`
  a2aBaseUrl: ""

The helm chart creates the k8s service of controller with <fullname>-controller.<namespace>.svc.cluster.local but the app and agent is still referencing http://kagent-controller.kagent:8083.

🔄 Steps To Reproduce

  1. helm install kagent-crds ./helm/kagent-crds/ --set kmcp.enabled=true --namespace kagent
  2. helm install kagent ./helm/kagent/ --namespace kagent --set providers.default=gemini --set providers.gemini.apiKey= --set kmcp.enabled=true --set kagents-tools.enabled=true --set tools.grafana-mcp.enabled=true --namespace kagent
  3. kubectl get svc --namespace kagent
  4. kubectl --namespace kagent exec deploy/promql-agent -it -- sh
  5. echo $KAGENT_URL

🤔 Expected Behavior

The result of echo $KAGENT_URL command should be http://<YOUR_RELEASE_NAME>.kagent:8083.

📱 Actual Behavior

The result of echo $KAGENT_URL command is always http://kagent-controller.kagent:8083
