// Walks a Notion-style paginated endpoint until the server says has_more=false
// or we've fetched `limit` pages (whichever comes first). The cap protects
// against pathologically long walks — the caller surfaces `truncated:true` so
// the user can re-call with a higher `page_limit` or a narrower query.
//
// `limit` is in PAGES, not items: a fetch-page typically returns up to 100
// items, so the default of 10 pages caps at ~1000 items.
