mamba3-research checkpoints

PyTorch checkpoints and intermediate tensors from the Mamba3 research project (wikitext quantization experiments, SISO/MIMO repro, tiny causal LM demo).

Layout mirrors the source repository:

• demo/wikitext_mamba3_quant/outputs/ - training checkpoints for QAT / ablation / nonlinear experiments
• demo/tiny_causal_lm/outputs/ - tiny causal LM weights
• artifacts/ - quantization test intermediates and model state dict
