feat: 打通录音核心链路,连接前后端命令
Some checks failed
Build Windows GUI / build-windows (push) Has been cancelled
Build Windows GUI / release (push) Has been cancelled

- 重构 capture.rs:添加 start_recording/stop_recording 支持真正的开始/停止控制
- 更新 AppState:引入 RecordingHandle 字段管理录音状态
- 重构 commands.rs:start_recording 立即返回,stop_recording 停止并保存文件
- 新增 recognize_file/recognize_last_recording 命令
- 前端 RecordPage:调用真实后端命令,监听 recording-stopped 事件自动识别
- 前端 FileConvertPage:连接 recognize_file 命令,支持导出识别结果
- 前端 SettingsPage:通过 save_config 持久化配置,支持配置加载
