Bug: generate-types emits invalid TS for queries with empty DESCRIBE QUERY schema (result: Array<{ ; }>)

Summary

@databricks/appkit type generation can emit invalid TypeScript in client/src/appKitTypes.d.ts when DESCRIBE QUERY returns no columns for a SQL query.

This produces output like:

result: Array<{
  ;
}>;

Environment
@databricks/appkit: 0.7.4
@databricks/appkit-ui: 0.7.4
TypeScript: 5.9.3
Build flow: Databricks Apps deployment (postinstall -> tsc -b -> vite build)
