claude suggests that you could consider using ts.forEachChild(node, visitor) just to avoid having the potentially confusing undefined third parameter for the TransformationContext. i think it's probably good to have it this way because we use visitEachChild elsewhere and it keeps us consistent, but, just mentioning

I think forEachChild works as well, changing the return value to ts.Node | undefined, though the iteration logic seems different, but looking more into it (tests pass with it however)

Summary by cubic
Detect the reserved __ctHelpers only when used as an identifier, instead of using a raw string check. This removes false positives from comments and similar names.
