fix: assets/drivers 目录缺失导致 Windows 构建失败

pubspec 声明了 assets/drivers/ 目录资产，但 dmg 被 gitignore 后整目录都不在
仓库里——全新 clone（Windows 机器）构建即报 "unable to find directory entry
in pubspec.yaml"。

修复：目录内提交 README.md 占位（随 git 保留目录），.gitignore 从忽略整目录
改为只忽略 assets/drivers/*.dmg。mac 打包机放 dmg 后行为不变；Windows 机器
目录为空可正常构建，向导自动降级为官网链接模式（bundledDmgPath 找不到 .dmg
返回 null 的降级路径已实现）。

+# HiTi Mac 驱动安装包目录
+
+此目录用于打包时**内置 HiTi macOS 打印驱动**（向导"一键安装驱动"功能的数据源）：
+
+- 构建 macOS 安装包前，把 `HiTiCardTypeMacDrivers_2.4.2.dmg`（约 25MB）放入本目录，
+  然后执行 `bash tool/package_macos.sh`——驱动会随 dmg 安装包分发
+- **dmg 文件本身不入 git**（.gitignore 已忽略 `assets/drivers/*.dmg`）
+- 缺少 dmg 时构建不受影响；向导会自动降级为"官网链接手动下载"模式
+- **Windows 不需要此目录放任何东西**（PavoApi 直打，驱动可选）
