Subject: [PATCH] fix: Fix QwenEmotion crash when json.loads returns
 string-valued emotion scores (#719)

* Initial plan

* Fix clamp_score to handle string emotion values from json.loads

* Add warning log for non-numeric emotion scores in clamp_score

* Raise ValueError on non-numeric emotion scores to abort TTS inference
