Proton/umu 的真实前缀是 <game_prefix>/pfx，PreFixPath 本身只是 compat data 目录（不含 drive_c 与 system.reg）。此前注册表改动、cryptbase、GameInput 与 wineboot 都作用在 PreFixPath 上，Wine 实际读不到，表现为鼠标点击无响应、 登录卡住。 - PathsList：新增 WinePrefixPath = PreFixPath/pfx - WinePrefix：Boot/ApplyWinegdkPrereqs/SetRefreshToken/RemoveRefreshToken 改用 WinePrefixPath；wineboot 补上 STEAM_COMPAT_DATA_PATH 与 STEAM_COMPAT_CLIENT_INSTALL_PATH - EasyLauncher：GameInput 与 cryptbase 的安装/检查改用 WinePrefixPath
部分镜像对 Range 请求返回 200 与整个文件，旧逻辑仍按分段偏移写入再拼接， 导致下载结果成倍膨胀却被判定为成功（ProtonGDK 组件损坏、解压报 Unknown block type 的根因）。 - 新增 RangeNotHonoredException；DownloadPartAsync 要求 206 且 Content-Range 与请求分段一致，并校验分段字节数 - DownloadPartWithRetryAsync 对该异常不再重试 - DownloadAsync 捕获后回退单线程下载（DownloadSinglePartAsync） - 合并与单线程路径统一改为先写 .part、校验总长度后原子替换，新增 MergeTempFilesAsync 与 TryDelete
Minecraft 的 RenderDragon 在图形初始化时会无条件初始化 AMD AGS，而 Wine 内置的 amd_ags_x64 读不出自身版本资源（err 1812），agsInit 恒返回失败，游戏反复重试后 卡死：窗口出现但无内容、主线程 100% CPU、界面无响应。 - 在 WinePrefix.ApplyWinegdkPrereqs 中写入 HKCU\Software\Wine\DllOverrides 的 amd_ags_x64=disabled - AGS 只是 AMD 的可选厂商扩展，禁用后游戏走"没有 AGS"的普通分支； 未加载该 DLL 的机器同样运行正常 - 实测：撤掉该 override 白屏必然复现，加回即恢复

Linux 下经 NeoLaunch（Proton/umu）启动游戏存在三处问题，本 PR 各修一处。
问题与修改
1. Wine 依赖与注册表写到错误目录（
d3c9d7b2）Proton/umu 的真实前缀是
STEAM_COMPAT_DATA_PATH/pfx，而PreFixPath本身只是 compat data目录（不含
drive_c与system.reg）。此前的注册表改动、cryptbase、GameInput、wineboot都作用在
PreFixPath上，Wine 实际读不到，表现为鼠标点击无响应、登录卡住。PathsList.WinePrefixPath = PreFixPath/pfxWinePrefix.Boot/ApplyWinegdkPrereqs/SetRefreshToken/RemoveRefreshToken、EasyLauncher的 GameInput/cryptbase 安装与检查全部改用WinePrefixPathwineboot补上STEAM_COMPAT_DATA_PATH与STEAM_COMPAT_CLIENT_INSTALL_PATH2. 多线程下载器不校验 Range（
748f2a54）部分镜像对 Range 请求返回
200+ 整个文件，旧逻辑仍按分段偏移写入再拼接，结果成倍膨胀却被判定为下载成功（组件损坏、解压报
Unknown block type的根因）。206且Content-Range与请求一致，并校验分段字节数，否则抛RangeNotHonoredExceptionDownloadAsync捕获后回退单线程下载.part、校验总长度后原子替换3. Wine 内置
amd_ags_x64导致 AGS 初始化死循环（db8a91c3）RenderDragon 在图形初始化时会无条件初始化 AMD AGS，而 Wine 内置的
amd_ags_x64读不出自身版本资源（
err 1812），agsInit恒返回失败，游戏反复重试后卡死：窗口出现但无内容、主线程 100% CPU、界面无响应。
WinePrefix.ApplyWinegdkPrereqs写入HKCU\Software\Wine\DllOverrides的amd_ags_x64=disabled验证
wineboot、注册表、GameInput 均落在<game_prefix>/pfx，鼠标与登录恢复正常200+ 完整文件）复现，旧逻辑把 12 MB 写成48 MB 且返回成功；修复后提示"服务器未按 Range 返回分段，回退单线程"，产物大小与哈希均正确
err:amd_ags:get_ags_version_from_resource ... err 1812在日志里重复 3000+ 次、主线程 100% CPU）；加回后amd_ags报错 0 行，渲染线程正常启动并进入网络/登录阶段
已在两个设备上验证通过
