docs(readme): add AI-generated & untested disclaimer

Mirrors the disclaimer in traefik-keycloak-openshift-gitops: states the repo was generated by Claude Opus 4.8, that validation is limited to helm template/lint and offline checks, and that no live install or end-to-end auth flow has been exercised.

+> ⚠️ **AI-generated & untested — read before using.**
+> This repository was **generated by Claude** (Anthropic's Claude Code, Opus 4.8)
+> while designing a portable, multi-distribution Helm layout for Traefik + Keycloak.
+> It has **not been deployed or tested on a real cluster** — neither OpenShift,
+> RKE2, k3s, kubeadm nor Tanzu. Validation so far is limited to `helm template`,
+> `helm lint` and offline YAML/schema checks —
+> **no live install, no end-to-end auth flow has been exercised.**
+> Treat it as a reviewed starting point: read every manifest and values file,
+> replace the dummy values (domains, realms, client secrets, LB pools, image
+> registries), and validate in a non-production environment before any real use.

 A single **umbrella Helm chart** that deploys the **official Traefik chart**
 (vendored) behind a **LoadBalancer**, with the Traefik **dashboard authenticated
 against Keycloak** (oauth2-proxy + ForwardAuth) and **restricted by role**
