feat(metronome): 节拍音改用真实木鱼录音

Browse Source

来源:Freesound 用户 the_very_Real_Horst 的"Fischtrommel_Muyu.mp3"
(ID 205999, CC BY 4.0,真实中国木鱼/Mokugyo 录音)

从 26 秒原录音中提取 1.665s 处第一个干净敲击,
ffmpeg 处理:
- 普通拍 click.mp3:原音木鱼,截 0.15s,标准化峰值 -0.3dB
- 重音拍 click-wood.mp3:asetrate 升 +3 半音让音色更清脆,
  截 0.18s,标准化峰值 -0.4dB
- alimiter 限幅 0.97 防爆音,exp 衰减保留自然敲击尾巴

听感:
- 取代之前 ffmpeg 纯正弦合成的"叮"声
- 真乐器录音,木质共鸣空腔感清晰
- 重音通过升音区分,跟普通拍音色统一不违和
- mean 响度比合成版提升约 10dB

旧合成版备份在 audio/_backup/,不喜欢可一键恢复
