refactor: 训练模块整体迁入分包,减小主包体积

主包超出 2MB 上限无法上传发布版,把训练相关全部移到独立分包。

目录调整:
- pages/training/* → training/pages/*
- hooks/use{Metronome,VoiceCoach,TrainingSession,TrainingBgm}.ts
  → training/hooks/*
- static/training/* → training/static/*
- 主包 hooks/ 目录已清空,所有 use* 都被分包独占

引用路径更新:
- 分包内 hook import 用相对路径 ../hooks/xxx,不依赖 @/ alias
- 资源路径 /static/training/audio/click.mp3
  → /training/static/audio/click.mp3
- useMetronome 默认 clickSrc / useVoiceCoach VOICE_BASE
  / useTrainingBgm BGM_BASE 全部对齐新路径

pages.json:
- 主包 pages 移除 training/index 和 training/metronome
- subPackages 新增 root="training",含 pages/index 和 pages/metronome
- 跟现有 TUIKit / doctor 分包风格一致

调用方:
- components/dev-training-entry navigateTo URL 更新成
  /training/pages/metronome (此组件留在主包,主包跳分包是合法操作)

文档/工具同步:
- training/static/README.md 路径示例改为 training/static/...
- scripts/generate-voice.mjs VOICE_DIR 与提示输出对齐新路径

Git mv 检测到的全是 rename(R),历史完整保留。
分包总体 80K(pages 44K + hooks 20K + static 16K),主包瘦身明显。
