/**
* 上传去重 / 幂等工具(Issue #1714)
*
* 背景:同一文件被反复入队、complete 超时后盲目重传,导致后端创建大量重复
* PROCESSING 素材记录。本模块提供两类纯函数:
*
* 1. 文件指纹:
* - makeFileFingerprint():文件名+大小+lastModified,入队去重用(同步、零开销)
* - computeFileHash():SHA-256 内容哈希(小文件全量、大文件抽样头尾),
* prepare/complete 时发给后端打开 file_hash 去重闸门
* 2. 队列去重:findDuplicateInQueue() 判断文件是否已在队列中
* 3. 幂等 token:makeClientUploadId() 生成上传幂等 ID(每次"一次逻辑上传"一个,
* 重试复用同一 ID,重新入队才生成新 ID)
*/
