feat: 宪法层四项完善 - 条款拆分/SHA3-384哈希/L3对接/nac_lens协议

1. 条款文件拆分：amendments.cnnl -> 6个独立章节文件
   - infrastructure.cnnl (A04-A08)
   - asset_compliance.cnnl (A09-A16)
   - governance.cnnl (A17-A24)
   - xtzh_currency.cnnl (A25-A32)
   - jurisdiction.cnnl (A33-A38)
   - ai_compliance.cnnl (A39-A43)

2. constitution_hash 升级：新增 calculate_constitution_merkle_root()
   使用 SHA3-384 计算所有激活条款的 Merkle 根（48字节/96位十六进制）

3. L3 存储层对接：state_database_ext.rs v2
   - 新增 ConstitutionClauseId 枚举（A01-A56 完整56条）
   - constitution_ref 字段类型安全验证
   - ConstitutionRefValidator 验证器

4. nac_lens 协议对接：constitution-service main.rs v2
   - 8个 nac_lens 方法（verify_clause/get_hash/issue_cr等）
   - TCP 监听 22050 端口
   - 完整请求/响应结构体
