## Summary by CodeRabbit

* **New Features**
* Added query expression optimization feature with a new `optimizeExpr`
configuration flag to enable automatic simplification of filter
predicates, including range predicate optimization, merging of IN/NOT IN
conditions, and flattening of nested logical operators.

* **Bug Fixes**
* Adjusted delete operation behavior to correctly handle expression
evaluation.
