### 性能优化 - 后端任务执行从串行锁改为 ThreadPoolExecutor 并发执行(默认3线程) - 添加 GZipMiddleware 响应压缩 + Nginx gzip 配置 - 数据库连接池参数优化(pool_size=10, max_overflow=20) - 视频帧提取并行化(ThreadPoolExecutor) - LLM 重试配置缓存到实例,避免每次请求读 env var - 前端路由级代码拆分(React.lazy + Suspense) - Vite manualChunks 拆分 markdown/markmap/vendor - MarkdownViewer 用 React.memo + useMemo 减少不必要渲染 - NoteHistory Fuse.js 实例 useMemo 缓存 - useTaskPolling 无待处理任务时跳过轮询 - 移除 antd 依赖(NoteForm Alert、modelForm Tag),改用 shadcn/ui ### 前端转写器配置(新功能) - 新增 TranscriberConfigManager(JSON 文件存储,替代环境变量) - 新增 GET/POST /transcriber_config API 端点 - 新增 GET /transcriber_models_status 模型下载状态查询 - 新增 POST /transcriber_download 后台模型下载触发 - 前端转写器设置页面:引擎选择、模型大小选择、模型下载管理 - deploy_status 端点同步从配置文件读取 ### Bug 修复 - 修复任务进行中切换页面后进度丢失:Home.tsx status 派生逻辑补全中间状态 - 修复 MLX Whisper 静默回退 fast-whisper:移除环境变量门控,macOS 下自动尝试导入 - MLX Whisper 不可用时抛出 RuntimeError 而非静默回退 - 前端展示 MLX Whisper 可用性状态,不可用时禁用保存 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
