Pull Request Overview

This PR optimizes the BuildGlobResultFromIncludeItem method to reduce memory allocations by replacing LINQ operations with more efficient manual iteration and array initialization patterns.

• Replaces LINQ Select().ToImmutableArray() with direct array allocation and population
