+    [WTF] Refactor EnumTraits to improve constexpr evaluation and handling of signed enums
+    https://bugs.webkit.org/show_bug.cgi?id=287370
+    rdar://144487521
+    
+    Reviewed by Keith Miller.
+    
+    This patch:
+    1. Removed unnecessary forConstexpr, replacing it with std::index_sequence for
+       better compile-time performance.
+    2. Improved handling of signed enums by introducing enumNamesMin and enumNamesMax,
+       ensuring min and max values are within the valid range of the underlying type.
+    3. Optimized the computation of enumNamesSize to prevent overflow and ensure
+       correctness for signed and unsigned enums.
+    4. Updated enumName lookup logic to correctly compute indices for signed enums
+       using unsigned arithmetic.
+    5. Added new test cases to cover signed and unsigned enums, including cases with
+       negative values, large gaps, and out-of-range lookups.
+    
+    This change ensures robust handling of enums with various underlying types, prevents
+    unexpected overflows, and enhances overall constexpr evaluation efficiency.
