feat(AI): 集成MNN推理引擎替换MLX作为主AI运行时 - 引入MNN(alibaba) + Arm SME2 + CPU作为主AI运行时，支持A19/iPhone17的 SME2和A17的NEON加速 - 添加MLX Swift作为兜底GPU推理方案，实现双后端切换机制 - 使用单一Qwen3.5-2B多模态模型(1.2GB)，替代原有的LLM+VL分离架构 - 实现InferenceEngine.current引擎选择逻辑，真机默认MNN，模拟器回退MLX - 更新AIAgent架构，通过MNNLLMBridge(ObjC++) → MNNBackend进行推理 - 修改队列机制防止并发推理导致OOM，使用信号量闸门控制显存占用 - 更新文档中的技术栈说明、模块边界和周次交付计划 ```
