/**
 * 响应式尺寸 Hook
 *
 * 用于计算图表的响应式宽度和高度，并监听窗口大小变化。
 * 在移动端（宽度 <= 768px）时自动调整为全宽和自适应高度。
 *
 * @param {number | string} width - 图表宽度，默认600px
 * @param {number | string} height - 图表高度，默认400px
 * @returns {object} 包含响应式尺寸和移动端标识的对象
 *
 * @example
 * ```typescript
 * const { responsiveWidth, responsiveHeight, isMobile } = useResponsiveSize(800, 400);
 * ```
