APNG IDAT/fdAT 分块流式 deflate 回放与 dispose 方法帧时序分析器

上传 PNG/APNG，解析动画结构：PNG 签名与逐块 CRC32 校验、IHDR（位深/颜色类型/隔行）、acTL（帧数与播放次数，必须位于首个 IDAT 之前）、fcTL（序号、区域约束 x+y+w+h ≤ 画布、delay_num/delay_den 归一化、dispose_op none/background/previous、blend_op source/over）、IDAT 首帧 + fdAT 后续帧；共享的 fcTL+fdAT 序号必须从 0 连续递增；逐帧回放 deflate 流并核对解压尺寸 = 高 × (1 + 每行字节数)，报告 zlib 损坏；dispose 语义模拟提示首帧 previous 视作 background、零延迟帧等。
