Add NOTES.txt for Helm chart post-install guidance

[ChrisJBurns]

Summary

The operator Helm chart does not include a NOTES.txt template. After helm install, users see no post-installation guidance about how to verify the operator is running, create their first MCPServer resource, or check logs for issues.

This is a missed opportunity to improve the first-run experience and reduce support burden. Most production Helm charts include NOTES.txt to print actionable next steps.

Severity: CONSIDER
Area: Helm Chart
Breaking: No

Location

• deploy/charts/operator/templates/ (missing NOTES.txt)

Recommended Fix

1. Create deploy/charts/operator/templates/NOTES.txt with content covering:
   • How to verify the operator pod is running (kubectl get pods -n {{ .Release.Namespace }})
   • How to check operator logs
   • A minimal MCPServer example to get started
   • Link to documentation for advanced configuration
2. Use Helm template variables for namespace and release name so the instructions are copy-pasteable.
3. Test the output with helm install --dry-run to verify formatting.

I'd like to work on this — opened PR with post-install NOTES.txt and helm-unittest coverage. The notes include copy-pasteable kubectl commands, a minimal fetch MCPServer example, and links to operator docs/examples.
