This PR refactors a lambda expression that contained unnecessary braces around a single-statement body, converting it into a more concise expression-bodied form to improve readability and maintainability.
- Consider simplifying lambda when its body has a single statement: The original lambda used a block body with braces and a single call to Execute, which is verbose for a one-line operation. We removed the braces and semicolon, converting it into an expression-bodied lambda (`static (spc, pair) => Execute(spc, pair.Left, pair.Right)`) to simplify the code and follow best practices.
