Ollama 0.40.5-rc1

• ci: shorten Windows Vulkan build path

Keep the nested shader-generator compiler probes below Windows path limits in checkouts with longer repository names.

• mlx: fix Nemotron bugs and support global scales

Accept published Nemotron layer names while retaining legacy aliases, and
fix layer-count inference and detached MTP quantization. Stabilize Mamba
softplus, preserve FP32 vision normalization, and compile Mamba gate and
norm scaling.

Support per-expert F32 global scales and preserve activation-scale
companions in ModelOpt and compressed-tensors NVFP4 imports. Normalize
reciprocal globals and reject invalid scales. Keep activation scales
separate from weight-only inference.

• mlx: add Nemotron 3.5 Super

• minor adjustments
