feat(audio): 使用 oto/v3 重构音频播放系统，移除 beep/v2 依赖

核心变更:
- 实现全局 oto.Context 单例管理（sync.Once）
- 实现一次性播放：PlayWav/PlayMP3（支持 context 取消）
- 实现 BGM 循环播放：PlayMP3Loop（atomic.Bool + WaitGroup）
- 迁移所有业务层到新 API（TTS/BGM/待机音频）
- 添加完整的单元测试（6/6 通过）

技术栈:
- oto/v3 v3.3.2（低级音频播放）
- hajimehoshi/go-mp3 v0.3.4（MP3 解码）
- youpy/go-wav v0.3.2（WAV 解码）

移除依赖:
- gopxl/beep/v2 及所有相关依赖

优化:
- 流式播放，无需预先加载
- 并发安全，无竞态条件
- 资源管理清晰（defer cleanup）
- Sleep 间隔优化（1ms → 10ms，降低 CPU 占用）
