List and Paginate

Goal: Enumerate the objects under a prefix without buffering the whole list into memory.

When to use this: Anytime you need to walk objects — copying a tree, building an index, finding the latest, summarizing a directory.

Recipe

ovstorage_list returns one page. You drive pagination by passing next_page_token from the prior response back as page_token on the next call. Stop when next_page_token is absent (or null).
