mmx music cover bug

[oxygen26]

input:
mmx music cover --prompt "cute boy vocal" --audio-file mmx_music_generate.mp3 --lyrics-file yy.txt --out zz.mp3

error:
Error: API error: invalid params, biz error: code=400, msg=amadeus play err, ttm fail, err = Cover mode requires dtw_result, beat_result, and audio_duration in the request (HTTP 200)

看了一下文档似乎是翻唱有一步音频前处理？cli里没有相关代码，可能是后台api的bug？

Closing as fixed in the current main branch. Music cover now runs the preprocess flow where needed and recent music fixes landed through #160, #196, and #197. Please reopen with a fresh reproduction on mmx-cli >= 1.0.17 if this still fails.
