pipeline.models[key] is None at patch time for GGUF Trellis2 pipelines
(Aero-Ex/ComfyUI-Trellis2-GGUF) that lazy-load the flow DiT inside the
sampler. nn.Module.__setattr__ only routes real Modules into _modules, so
self.inner = None became a plain __dict__ attribute that nn.Module.__getattr__
never searches, and the fallback raised 'object has no attribute inner'.
- store inner via _set_inner: real Modules stay registered submodules, None/
lazy placeholders are kept as a plain attribute; __getattr__ resolves both
- clear errors when a compute step / attribute access hits an unloaded model
- bind_inner(model) to attach the real DiT once it materializes
- _LazyPatchDict binds the model transparently when the sampler assigns it
into pipeline.models[key] (TRELLIS repos), so the cache survives lazy load
