Two fixes for dual-expert 14B sampling:
1. FreeNoise color shift (bernini_sampling.py)
- Clone noise before FreeNoise shuffling so differential diffusion
uses original i.i.d. noise (model trained on i.i.d.).
- FreeNoise-shuffled noise only for k-diffusion x_T initialization.
2. RAM not released after model unload (model_manager.py)
- BerniniRModelHandle.unload() now calls release_model_ram() before
mm.unload_model_and_clones, replacing all parameters with empty
tensors via module._parameters[key] = empty(0).
- Fixed _make_low_wrapper closure dropping high_model reference via
nonlocal, causing the cleanup loop to call None.unload().
