feat: add Helm chart scaffolding and core templates
Add initial Helm chart under dist/chart/ with core templates that produce the same resources as the kustomize deployment: - Chart.yaml, values.yaml, .helmignore - CRD (crds/mcp.x-k8s.io_mcpservers.yaml) - ServiceAccount (conditional via serviceAccount.create) - RBAC: manager ClusterRole/Binding, leader-election Role/Binding, metrics-auth ClusterRole/Binding, metrics-reader ClusterRole (conditional via rbac.create) - Controller manager Deployment with configurable image, resources, nodeSelector, tolerations, affinity, podAnnotations, podLabels - Metrics Service (port 8443) - NOTES.txt with post-install instructions - _helpers.tpl with standard naming/labeling helpers Part of #132 Signed-off-by: Venkatesh1505 <venkyravi97@gmail.com>

1. Verify the operator is running:

kubectl get deployment -n {{ .Release.Namespace }} {{ include "mcp-lifecycle-operator.fullname" . }}-controller-manager

2. Create an MCPServer resource:
