 * A shader node that provides time-based functionality for shaders.

 *
 * The node includes both GLSL and WGSL implementations to support different
 * graphics APIs (WebGL and WebGPU).
 *
 * @example
 * ```typescript
 * const timeNode = new TimeShaderNode();
 * // Use timeNode.outValue in your shader graph for time-based effects
 * ```

     * effects such as animations, oscillations, or procedural variations.
