The index parameter should be validated to ensure it's non-negative and within valid bounds (typically < MAX_VERTEX_ATTRIBS, usually 16 or 32 depending on implementation). Invalid index values could cause undefined behavior in the underlying OpenGL calls.

The index parameter should be validated to ensure it's non-negative and within valid bounds (typically < MAX_VERTEX_ATTRIBS). This matches the validation pattern needed in vertexAttribI4i.

Suggested change
// Validate index parameter
constexpr int MAX_VERTEX_ATTRIBS = 16; // WebGL2 minimum, replace with actual value if available
if (index < 0 || index >= MAX_VERTEX_ATTRIBS) {
isolate->ThrowException(Exception::RangeError(
String::NewFromUtf8(isolate, "vertexAttribI4ui: index out of range").ToLocalChecked()));
return;
}

The index parameter should be validated to ensure it's non-negative and within valid bounds (typically < MAX_VERTEX_ATTRIBS). This validation is missing across all four methods.
