v3.12.2 任务数据更可控，大批次更流畅，转写诊断更完善

feat

• 诊断包导出窗口新增「Whisper 转写诊断」（Windows / Linux）：用内置短音频在独立进程中单独测试 Vulkan / CPU 后端与 VAD 开关，原生库崩溃也不影响应用；结果和 Windows 显卡驱动版本随诊断包导出，便于定位 GPU 加速闪退
  Add "Whisper transcription diagnostics" to the diagnostics export dialog (Windows / Linux): test the Vulkan / CPU backend and the VAD switch on a short built-in clip in an isolated process, so a native crash cannot take the app down. Results and the Windows GPU driver version are exported with the diagnostics package to help pin down GPU acceleration crashes

perf

• 大批次任务更流畅：进度更新合并发布，文件很多时列表只渲染可见部分，日志面板只保留最近 200 条，缓解批量处理上百个文件时的界面卡顿 (#574)
  Smoother large batches: progress updates are coalesced, long file lists render only the visible rows, and the log panel keeps the latest 200 entries, easing UI lag when processing a hundred or more files (#574)

fix

• 修复 3.12 起任务工作文件被写入应用数据目录（如 C 盘）、忽略存储目录设置且从不清理的问题：新任务结果跟随「统一存储目录」，临时文件改用临时目录下的短路径，并在阶段结束或删除任务后自动回收 (#579)
  Fix task working files being written to the app data directory (e.g. the C drive) since 3.12, ignoring the storage directory settings and never being cleaned up: new task results now follow the unified storage directory, temporary files use short paths under the temporary directory, and unneeded files are reclaimed automatically when a stage finishes or a task is deleted (#579)
• 「设置 → 存储位置」新增「任务数据」：查看占用空间、清理无用任务文件，并把旧任务数据迁移到新位置（下次启动时执行，校验无误后才删除旧副本） (#579)
  Add "Task data" under Settings → Storage location: view disk usage, clean up unused task files, and migrate existing task data to the new location, which runs on the next launch and deletes old copies only after verifying the new ones (#579)
• 修复 faster-whisper 模型缺少词表文件时仍被视为已安装、转录报「Cannot load the vocabulary」错误的问题：现在会提示模型不完整，重新下载即可补全，导入不完整的模型文件夹也会被拒绝并指明缺失文件
  Fix faster-whisper models missing a vocabulary file being treated as installed and failing with "Cannot load the vocabulary": they are now reported as incomplete so downloading again repairs them, and importing an incomplete model folder is rejected with the missing file named
• GPU 加速包（CUDA / Vulkan）下载后先校验 SHA-256 再安装：校验失败自动换下载源；新包校验并解压成功后才替换旧版本，失败时保留原有安装；诊断包会记录加速包的来源与版本
  GPU acceleration packages (CUDA / Vulkan) are now verified by SHA-256 before installing, and other download sources are tried if verification fails; a new package replaces the old one only after it is verified and extracted, otherwise the existing install is kept; the diagnostics package also records each package's source and version
• 修复通过桌面启动器打开应用时，因日志管道被关闭而在转录中弹出「write EPIPE」报错的问题 (#572)
  Fix the "write EPIPE" error popping up during transcription when the app is opened from a desktop launcher that closes its log pipe (#572)
• 主界面意外退出（白屏）后弹出恢复提示，可一键重新加载界面，后台任务不受影响；白屏的根本原因仍在排查 (#574)
  When the main window exits unexpectedly (white screen), a recovery prompt now offers a one-click reload without affecting background tasks; the root cause of the white screen is still under investigation (#574)
