Support negative

Why it matters

This feature allows users to access tuple elements using negative indexes, similar to Python-style indexing. It simplifies retrieval of elements from the end of a tuple, enhancing query flexibility and convenience.

How to use it

Users can now access tuple elements with negative indexes directly in their queries. For example, to get the last element of a tuple, use tuple.-1. This requires no additional configuration and is available by default after updating to the version including this feature.
