/**
 * @webdrop/core:WebDrop 的端到端加密核心。
 *
 * 前端只需要这几件事:
 *   ChannelSession.create(...)       创建频道,得到会话、POST /channels 的请求体和请求头、分享链接
 *   ChannelSession.open(link)        打开链接,得到会话
 *   session.authHeaders(role)        所有请求要带的头
 *   session.encryptText/Json/File    把内容加密成可直接 POST 的帧
 *   session.createItemReader()       喂入 WebSocket / log 的记录,得到解密后的条目
 *   session.decryptItemStream()      流式解密大文件
 *
 * 本包只依赖 WebCrypto,不含 UI,不发网络请求,不处理重连和队列。
