Thanks, this is great! We currently don't have a CI/CD test for QuestDB. Do you think it would be possible to add one first before adding new features?

Syntax errors are always unexpected, so we should fix this in the generator.

I think we should only add new features once we have a CI/CD that works for a given QuestDB version.

This PR adds initial support for QuestDB in SQLancer.
Changes included:
QuestDBQueryGenerator.javato generate simple SELECT queries.QuestDBProvider.javato use the new generator.--num-threads 1) for stability during testing.Currently, only basic SELECT queries are supported. INSERT, DELETE, and more complex queries will be added in future iterations.
This addresses Issue #457 and lays the foundation for full QuestDB testing support.
