Add Claude slash command for creating a dev env

[sridhargaddam]

Add "/setup-dev-env" command for setting up a local dev environment with KIND for sidecar as well as ambient profiles.

Key changes:

• The "/setup-dev-env" supports both sidecar and ambient profiles.
• The sail operator, built from local source code is deployed to the kind cluster.
• Sample apps (sleep and httpbin) are installed using the kustomization files.
• Connectivity is validated using the sample apps.
• A short summary along with some useful next steps is suggested at the end of the command run.

SUMMARY
- KIND cluster created
- Sail Operator deployed (local build)
- IstioCNI daemonset running
- Istio control plane ready
- ZTunnel daemonset running
- Sample apps deployed (ambient mode)
- Connectivity test passed
- mTLS working (L4 via ztunnel)
- Ambient mode fully operational

NEXT STEPS

1. Export KUBECONFIG for your shell:
   export KUBECONFIG=/tmp/tmp.BDo4GiYInT/config

2. Test additional endpoints:
   kubectl exec -n sample deploy/sleep -- curl http://httpbin.sample:8000/get

3. Deploy waypoint for L7 features:
   istioctl waypoint apply -n sample
   kubectl label namespace sample istio.io/use-waypoint=waypoint

4. Deploy bookinfo sample:
   kubectl label namespace default istio.io/dataplane-mode=ambient
   kubectl apply -n default -f https://raw.githubusercontent.com/istio/istio/master/samples/bookinfo/platform/kube/bookinfo.yaml

5. Check ztunnel workloads:
   istioctl ztunnel-config workloads
