主要改动： 1. TCP缓冲区优化（16MB）- 解决公网上传速度慢问题 2. 并发数降低到1-3 - 避免4并发导致ERR_CONNECTION_RESET 3. 动态并发控制 - 根据网络环境自动调整 4. Nginx超时增加到120s - 支持大分片上传 5. 上传进度修复 - 修复剩余时间计算 6. 新增任务-页面上传器和详情组件 7. 统一部署文档为deploy-remote-build.ps1 问题修复： - 公网用户上传从200-900KB/s提升到预期3-5MB/s - 内网用户上传更稳定，无连接重置错误 - UploadProgress组件剩余时间计算修正 Co-Authored-By: Claude <noreply@anthropic.com>
