问题：#686引入了bash数组语法 FFMPEG_SOURCES=(...)，但worker基础镜像
的/bin/sh是dash，不支持数组，导致Worker Build报
Syntax error: "(" unexpected

修复：
- 移除数组，改用 for src in "url1" "url2" "url3"; do 的纯sh写法
- 所有语法保持POSIX sh兼容，确保dash下能正常运行
- 保留所有原有功能：三源重试、tar校验、坏包清缓存、二进制校验

+# 注意：必须用纯sh语法（dash兼容），不能用bash数组、[[ ]]等特性
 # 修复策略：1.三源下载 2.tar完整性校验 3.损坏删缓存重试 4.二进制可执行校验
