"""Patch a Transformers 5.0.0 Qwen3-Omni config init ordering bug.
The local build reads `self.use_sliding_window` inside
`Qwen3OmniMoeTalkerCodePredictorConfig.__init__` before `PreTrainedConfig`
has copied unknown keyword arguments onto the instance. ModelScope's Instruct
config includes `use_sliding_window`, but the attribute is not available yet.
Setting it before the original initializer keeps the upstream behavior while
allowing local `from_pretrained()` to proceed.
