* test(e2e): add ECR end-to-end suite (control plane + docker/crane/skopeo)
New tests/e2e/ecr/ suite plus harness support:
- harness: ECR SDK client, control-plane helpers (repo CRUD, get-login-password,
describe-images), and docker/crane/skopeo CLI wrappers that skip when the
binary or registry-host resolution is absent.
- suite: control-plane CRUD + policy + lifecycle round-trip; docker login/push/
pull; crane append/pull and skopeo copy exercising the Bearer /v2/token flow.
- registered e2e-ecr in the Makefile + service manifest.
Predastore capacity/load leg is a skipped placeholder pending mulga-siv-359/356.
* test(e2e): carry awsgw port in ECR registry host for dev clusters
Dev clusters bind awsgw on a non-standard port (e.g. 9999); production uses
:443. ECRRegistryHost now appends SPINIFEX_ECR_PORT when set so docker/crane/
skopeo address the right endpoint, and RequireRegistryResolves strips the port
before DNS lookup.
