Ordered artifact database queries now report their ordering and warn when more results may exist

What

An Artifact can hold a small database of documents that Claude can query. Two things change when Claude runs one of these queries with order_by, which sorts the results by a chosen field:

• The result now includes ordered_by: {field, limit}. This repeats the field the results were sorted by and the limit that was actually applied, including a limit Claude did not set itself.
• Ordered queries return a single page. When that page is full, the tool output warns that more results may exist beyond the ones shown. It tells Claude to raise query.limit, or to drop query.order_by and page through the results with query.cursor.

Why

Before, an ordered query gave no sign that it had stopped at a limit, so Claude could treat a partial list as the complete set. Claude now sees the limit that was used and is told how to fetch the rest.
