  set num_ctx 32768 (fits 70B in 64GB with safe headroom)
- Update Codestral-22B and Qwen3-32B Modelfiles
- Add Modelfiles for all models in ~/Models/LLM and ~/Models/MLX:
  EVA-LLaMA-3.33-70B, Midnight-Miqu-70B, QwQ-32B, Qwen3.5-35B,
  Qwen3-Coder-30B, Qwen3-Coder-Next, Qwen3-VL-30B, GLM-4.6V-Flash,
