Subject: [PATCH] refactor: migrate from ingress-nginx to Traefik v3

Replace ingress-nginx 4.15.1 with Traefik v3 (Helm chart 39.0.7)
as the ingress controller for the local kind cluster.

- Replace k8s/nginx/ with k8s/traefik/ (Helm chart, values, namespace)
- Update setup script selectors and namespace references
- Convert nginx upstream-vhost annotations to Traefik Middleware CRDs
- Update ingressClassName from nginx to traefik
- Add .claude/ to .gitignore
