• This changes the existing iterator API from lazy to eager: generate() now runs when manifest_destroy() is called, rather than when the returned iterator is first consumed. That makes configuration side effects, logging, and parse/path errors occur earlier for existing callers. Preserve the previous generator semantics by delegating with yield from.
