feat: operator v0.1.16 — job stdout -> status.Message (feature B)

- FunctionJobReconciler: added KubeClient field (kubernetes.Interface)
- getJobPodOutput(): reads pod logs via typed client after job succeeds
- main.go: inject kubernetes.NewForConfigOrDie into FunctionJobReconciler
- rbac.yaml: add pods/pods/log get/list/watch permissions
- examples/simple-python/: job->function chain demo (Python)
- examples/simple-node/: job->function chain demo (Node.js)

sless_job.X.message now contains the return value of the function
