fix: align tests and deployment templates with core v0.3.0 (#7)

Restore the build and Kubernetes conformance after the core v0.3.0 upgrade:

- Pass the RuntimeContext argument now required by
  network.GenerateNetworkMappings in the create-to-run test.
- Harden the deployment template to satisfy the
  KUBERNETES_OUTPUT_PROFILE_EPHEMERAL_LOCAL_APPLY_V1 and restricted
  conformance profiles: pod/container securityContext, resource bounds,
  liveness/readiness/startup probes, terminationGracePeriodSeconds and
  automountServiceAccountToken, digest-pinned image, and secretKeyRef-based
  secret injection under restricted profiles.
- Pin the workload to numeric UID 1000 (deployment runAsUser + Dockerfile
  adduser). Kubernetes' runAsNonRoot admission check rejects a container
  whose image user is a non-numeric name, so runAsNonRoot alone would leave
  every deployed pod stuck in CreateContainerConfigError.
- Mount an emptyDir at /tmp so the container has writable scratch space under
  readOnlyRootFilesystem.
- Label the owned Namespace with app.kubernetes.io/managed-by: codefly and
  elide the inline Secret under restricted profiles.
- Assert the rendered deployment pins runAsUser and mounts /tmp so these
  runtime requirements can't regress silently past static conformance.
