feat(nac-ai-valuation): 完成AI资产估值系统核心模块
- 实现12种资产类型分类（不动产、大宗商品、金融资产等） - 实现8个辖区支持（US, EU, China, HongKong, Singapore, UK, Japan, MiddleEast） - 实现5个国际贸易协定（WTO, SCO, RCEP, CPTPP, USMCA） - 实现AI模型集成层（ChatGPT-4.1, DeepSeek-V3, 豆包AI-Pro） - 实现协同仲裁算法（加权投票70% + 贝叶斯融合30%） - 实现动态权重计算器（根据辖区和资产类型自动调整） - 实现异常值检测（IQR方法） - 实现完整的估值引擎（ValuationEngine） - 所有单元测试通过（11个测试用例） 技术栈： - Rust 1.83.0 - tokio异步运行时 - rust_decimal高精度计算 - serde序列化 - anyhow错误处理
