The dashboard app build aliases "@fusion/core" to its types-only entry
(core/src/types.ts), which doesn't re-export builtin-workflows, so the Vite/
Rollup bundle failed on `import { isBuiltinWorkflowId } from "@fusion/core"`
(tsc/vitest resolve it via source/dist, so they passed — only the production
build caught it). Inline the one-line "builtin:" prefix check in the editor
instead of pulling the eager BUILTIN_WORKFLOWS construction into the browser
bundle.
