Optimize _BaseExpr.__mod__

The optimized code achieves a **21% runtime improvement** by **inlining the `_create_operator_expression` function call** directly into the `_overload_op` method. This eliminates function call overhead that was consuming 61.2% of the method's execution time in the original implementation.

**Key optimization:**
Instead of calling `_create_operator_expression(l, r, op_type)`, the optimized version constructs the result expression inline:
```python
new_expr = _BaseExpr()
new_expr._op = op_type
new_expr._children = l + r
return new_expr
```

**Why this is faster:**
1. **Eliminates function call overhead**: The original code spent 807μs (61.2% of method time) on the function call itself. The optimized version removes this entirely.
2. **Reduces tuple unpacking**: The original `_create_operator_expression` used `(*left_children, *right_children)` which requires unpacking and repacking tuples. The optimized version uses simple tuple concatenation `l + r`.
3. **Simpler execution path**: Fewer stack frames and attribute lookups result in tighter, more cache-friendly code.

**Test results show consistent improvements:**
- Basic operations: 18-24% faster across all test cases
- Edge cases with complex expressions: 20-24% faster
- Large-scale scenarios (700 combined children): 23.6% faster

The optimization particularly benefits workloads that frequently construct operator expressions, which is common when building complex query filters or database expressions. All behavioral semantics are preserved - the same children tuples are created and the same expression tree structure results.
