add Skaffold config with local-simple and local profiles

Create skaffold.yaml with two profiles:
- local-simple: plain k8s Deployments (no Knative needed)
- local: full Knative Services (production parity)

Both profiles support file sync for handler hot reload and automatic
port forwarding. Add images transformer to local overlay so Skaffold
can replace GHCR image refs. Add Make targets for both profiles.
