cli: resolve deployments by (name, kind), not bare name

Thread kind through every CLI resolver so a tool, service, and job can
share a name. Reads go through config.deployment(kind,name) /
deployments_named(name) / all_deployments(); writes target the per-kind
store (config.services/jobs/tools/statics). delete cascades over
(kind,name) tuples; run/info resolve via registry.named().
