Add compile-time query validation

✅ LGTM! No major issues found. Good to go!

The changes added a validation check for the query parameters limit, offset, and their sum to ensure they are non-negative. This check is now performed in both the Query constructor and in the query and watch methods of the QueryEngine. This will help to avoid potential errors in the future.

Additionally, the _validateQuery method has been added in the Query class to encapsulate this validation logic, making the code more modular and easier to maintain. Overall, these changes seem to improve the robustness of the code without introducing any significant issues or performance problems.
