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
