The deploy step did 'kubectl set image deployment/tidaldb' on every image
build, coupling image builds to a standalone roll. Deployment is manual via
kustomize from the orchard9-k3sf ops repo (its contract: no CI/CD deploy). The
one tidal-server binary serves both standalone and multi-process 'cluster
--region' modes, so this image covers the m8p10 3/3 cluster deploy too. Adds an
explicit 'm8p10' image tag for deterministic manifest pinning.
