## Description

Qwen3.8 Flash-Next/Qwen4-Exp three-model vision-language pipeline.

Reuses the source-identical Qwen3/Qwen3.5 packed vision encoder and
embedding mixer, while preserving the Qwen4-Exp decoder's independent PLE
token stream and heterogeneous recurrent, QSA, and position state.

## Usage

```bash
mobius build --model <MODEL_ID> output_dir/
```

```python
from mobius import build

model = build("<MODEL_ID>")
```
