 * Compares two 3D vectors using an epsilon value for floating-point comparison.

 * @param {ArrayVector3D} xyz2 - Second vector as `[x, y, z]`
 * @param {number} epsilon - Tolerance for comparison (default: `Number.EPSILON`)
 * @returns {boolean} `true` if the vectors are approximately equal, `false` otherwise
