Description

The Qwen3-TTS model is quite successful and supports the transformers library. It would be great if we could fine-tune it with Unsloth support.

Research direction
First, review how Unsloth currently integrates new models by examining the codebase, particularly under the unsloth/models directory. Look for similar model support for Qwen variants. Then, check the transformers library for the Qwen3TTS model class. The issue comments may contain additional guidance from maintainers. Implement the fine tuning wrapper following the established pattern, ensuring compatibility with Unsloth's optimization techniques.
