问题修复: - 修复解密超过 80MB 视频时页面崩溃的问题（issue #4 #6 #8） - 根因：旧实现将整段视频经 CDP 管道传入浏览器做 XOR，base64 膨胀后超过 Chromium DevTools 协议 100MB 单条消息上限，导致页面被关闭 - 将 XOR 解密从浏览器移至 Node.js 端，浏览器仅负责生成 128KB 密钥流， 视频数据不再进入浏览器，文件大小不再受此限制 新功能: - 新增 lib/decrypt.js 解密核心模块（decryptBuffer / assertMp4） - 新增 decode_key 密钥流 LRU 缓存，命中后跳过浏览器 WASM 调用， 可通过 KEYSTREAM_CACHE_MAX 环境变量配置上限（默认100） - 新增 test/decrypt.test.js 单元测试，覆盖 120MB 大文件边界场景 其他: - Dockerfile 补充拷贝 lib 目录，修复容器内模块缺失 - worker.html 的 decryptVideo 标注为已弃用（保留向后兼容） - 更新 README 架构说明，补充大文件故障排除与「如何获取 decode_key」说明 - 版本号升级至 2.1.0
