 * Walks EVERY stream matching `query`, paging with the keyset cursor.

 * `Store.query_streams` defaults to `limit: 100`, so a caller that wants
 * the whole table must page — passing no query silently truncates at the
 * first page, which is a false all-clear for anything that reports on
 * what it found.
 *
 * The cursor is the last stream name the callback saw; results are
 * ordered by stream name, so a short page means the walk is done.
 *
 * @param store - Store to walk.
 * @param callback - Invoked once per matching position, in name order.
 * @param query - Optional filter. A caller-supplied `limit` sets the page
 *   size (the walk still visits every match); `after` seeds the cursor.
 * @returns The total number of positions emitted.
