/**
 * Bare `UniformNode` adapter. Auto-detects `UniformNode` instances and exposes their `.value` for animation. Scalars and booleans animate via `value`, `Color` uniforms via `color`, and `Vector2/3/4` uniforms via `x` / `y` / `z` / `w` axes.
 *
 *   import 'animejs/bindings/three';
 *   import { uniform } from 'three/tsl';
 *   animate(uniform(0),              { value: 1 });
 *   animate(uniform(new Color()),    { color: '#0f0' });
 *   animate(uniform(new Vector3()),  { x: 1, y: 0.5 });
 *
 * `UniformNode` slots assigned to `NodeMaterial` (`material.colorNode`, `material.offsetNode`, ...) are auto-detected by the shared resolvers in `resolvers.js`. Non-uniform nodes (`mix`, `add`, computed expressions), `Matrix3/4` and `Texture` valued uniforms, and `UniformArrayNode` / `BufferNode` are out of scope and fall through to the engine's direct property path.
