fix(komoplane): set replicaCount to integer + kagentFix annotation [kagent/aire-agent]

[olegenii]

RCA:

The HelmRelease test/komoplane-20 failed during Helm install because the chart rendered a Deployment
with spec.replicas set to a string value. The HelmRelease contained replicaCount: o1 (letter 'o' + 1)
which is a string. Kubernetes expects replicas to be an integer (int32). The helm-controller reported:

• Deployment in version "v1" cannot be handled as a Deployment: json: cannot unmarshal string into Go struct field DeploymentSpec.spec.replicas of type int32

Remediation implemented:

• Replaced invalid string value replicaCount: o1 with integer replicaCount: 1 in apps/overlay/control-cluster/hr-failed.yaml.
• Annotated the HelmRepository and HelmRelease with kagentFix=2025-09-17T08:58:30Z per agent requirements.

Why this fix is safe:

• Changing replicaCount from a non-numeric string to a numeric integer corrects the type mismatch and allows Helm to render valid Deployment YAML.
• The change is scoped to the intentionally failing test overlay manifest (hr-failed.yaml) only.

Next steps and verification:

1. Merge this PR to the local branch. Flux will pick up the change and re-apply the HelmRelease.
2. Verify the HelmRelease status in namespace test: kubectl -n test get hr komoplane-20 -o yaml and confirm Ready condition.
3. Check helm-controller logs and events for successful install.
4. If the HelmRelease still fails, inspect rendered Helm template using helm template locally against the chart version 0.1.6 and the provided values.
