fix(upload): 修复流式上传中的文件名处理逻辑

- 修正预上传接口调用时传递正确的文件总数而非固定值-1
- 移除导入配置中文件分割时的文件扩展名保留逻辑
- 删除流式上传选项中的fileExtension参数定义
- 移除流式上传实现中的文件扩展名处理相关代码
- 简化新文件名生成逻辑，不再附加扩展名后缀

+## APT 缓存问题详解
+
+### 问题描述
+
+即使使用了 `--mount=type=cache,target=/var/cache/apt`，Dockerfile 中的 `apt-get update` 仍会尝试从网络获取包列表（list 数据），导致无网环境下构建失败：
+
+```
+Err:1 http://mirrors.aliyun.com/debian bookworm InRelease
+  Could not resolve 'mirrors.aliyun.com'
+Reading package lists...
+E: Failed to fetch http://mirrors.aliyun.com/debian/dists/bookworm/InRelease
+```
+
+### 根本原因
+
+- `--mount=type=cache,target=/var/cache/apt` 只缓存下载的 `.deb` 包
+- `apt-get update` 会尝试从配置的源获取最新的包索引（InRelease/Packages 文件）
+- `/var/lib/apt/lists/` 目录存储包索引，但通常不在缓存范围内
+
+### 解决方案
+
+#### 方案 1: 使用预装 APT 包的基础镜像（推荐）
+
+这是最有效的方法：
+
+**步骤 1**: 在有网环境构建预装所有依赖的基础镜像
+
+```bash
+# 构建并保存带 APT 预装包的基础镜像
+./scripts/offline/build-base-images.sh
+```
+
+这会创建以下预装基础镜像：
+- `datamate-java-base` - 用于 backend、gateway（预装 vim、python3、libreoffice 等）
+- `datamate-python-base` - 用于 backend-python（预装 openjdk、nfs-common 等）
+- `datamate-runtime-base` - 用于 runtime（预装 libgl1、tesseract-ocr 等）
+- `deer-flow-backend-base` - 用于 deer-flow-backend
+- `mineru-base` - 用于 mineru
+
+**步骤 2**: 在无网环境使用这些基础镜像构建
+
+```bash
+# 加载包含预装基础镜像的 tar 包
+docker load -i build-cache/images/base-images-with-apt.tar
+
+# 使用最终版构建脚本
+./scripts/offline/build-offline-final.sh
+```
+
+#### 方案 2: 修改 Dockerfile 跳过 apt update
+
+如果确定不需要安装新包，可以修改 Dockerfile：
+
+```dockerfile
+# 原代码
+RUN apt-get update && apt-get install -y xxx
+
+# 修改为（离线环境）
+# RUN apt-get update && \
+RUN apt-get install -y xxx || true
+```
+
+#### 方案 3: 挂载 apt lists 缓存
+
+在有网环境预先下载并保存 apt lists：
+
+```bash
+# 有网环境：保存 apt lists
+docker run --rm \
+    -v "$(pwd)/apt-lists:/var/lib/apt/lists" \
+    eclipse-temurin:21-jdk \
+    apt-get update
+
+# 无网环境：挂载保存的 lists
+docker build \
+    --mount=type=bind,source=$(pwd)/apt-lists,target=/var/lib/apt/lists,ro \
+    -f Dockerfile .
+```
+
+**注意**: BuildKit 的 `--mount=type=bind` 在 `docker build` 中不直接支持，需要在 Dockerfile 中使用。

+## 推荐工作流（解决 APT 问题版）
+
+### 工作流 A: 使用预装 APT 包的基础镜像（彻底解决 APT 问题）
+
+```bash
+# ========== 有网环境 ==========
+
+# 1. 构建并保存带 APT 预装包的基础镜像
+./scripts/offline/build-base-images.sh
+# 输出: build-cache/images/base-images-with-apt.tar
+
+# 2. 导出其他缓存（BuildKit 缓存、外部资源）
+./scripts/offline/export-cache.sh
+
+# 3. 打包传输
+scp build-cache/images/base-images-with-apt.tar user@offline-server:/opt/datamate/build-cache/images/
+scp build-cache-*.tar.gz user@offline-server:/opt/datamate/
+
+# ========== 无网环境 ==========
+
+cd /opt/datamate
+
+# 4. 解压
+tar -xzf build-cache-*.tar.gz
+
+# 5. 加载预装基础镜像（关键！）
+docker load -i build-cache/images/base-images-with-apt.tar
+
+# 6. 使用最终版脚本构建
+./scripts/offline/build-offline-final.sh
+```
+
+### 工作流 B: 简单场景（使用传统构建）
+
+如果 APT 包需求简单，可以直接使用传统构建：
+
+```bash
+# 有网环境
+make offline-export
+
+# 传输到无网环境
+scp build-cache-*.tar.gz offline-server:/path/
+
+# 无网环境
+tar -xzf build-cache-*.tar.gz
+make offline-diagnose        # 检查环境
+make offline-build-classic   # 使用传统构建
+```
