 * A shader node that handles attribute weight calculations in vertex shaders.

 * The node operates in the vertex shader stage and provides both GLSL and WGSL
 * implementations for cross-platform compatibility.
 *
 * @example
 * ```typescript
 * const attributeWeightNode = new AttributeWeightShaderNode();
 * // Use the node's output in shader composition
 * ```
