proposal: load local images into the local cluster

[atkrad]

Local kind (deployah cluster up) cannot pull private or freshly built images the way a laptop Docker daemon can. LoadImage already exists in internal/localkube. Nothing in the CLI calls it.

deployah cluster load-image myapp:dev
deployah cluster load-image --from-spec -e local

Reuse Manager.LoadImage (file, daemon, or pullable ref). Remind about imagePullPolicy when the tag is latest. --sync-registry-auth is for authenticated pulls, not this.

Remote clusters are out of scope. Building images is #26 / #27. A local registry sidecar can wait.

Related: #26, #27, #28, #41.

Cross-link: Kind-based e2e harness is tracked in #37 (follow-ups #38–#41).

Once that lands, prefer adding live load-image → deploy smoke on that suite instead of one-off manual Kind checks. #41 may also reuse LoadImage (via this CLI) to pin/preload the e2e workload image and cut registry flakes.
