fix(llmodels): don't evaluate on cluster seed before a model is selected

The basic form seeds a default cluster on open, which fired the full cluster-change handler and triggered an evaluate request before any model was picked. Split off a seed callback that refreshes scoped options without evaluating, and guard the evaluate handler with a model-selected check as a backstop.
