// NOTE: This file is intentionally mirrored in @n8n/expression-runtime/src/extensions/
// for use inside the isolated VM. Changes here must be reflected there and vice versa.
// TODO: Eliminate the duplication. The blocker is that @n8n/expression-runtime is
// Vite-stubbed for browser builds (to exclude isolated-vm), which prevents n8n-workflow
// from importing these extension utilities directly from the runtime package. Fix by
// splitting @n8n/expression-runtime into a browser-safe extensions subpath (not stubbed)
// and a node-only VM entry (stubbed).
