feat(constitution-layer): 部署宪法层服务到主网

- 新增 nac-constitution-service crate（宪法层 HTTP 服务）
- 实现 NAC 宪法七大原则验证引擎
- 实现宪法收据生成系统（ConstitutionalReceipt）
- 实现宪法状态树（创世宪法哈希 SHA3-384）
- 严格遵循 NAC 原生类型系统：Address 32B / Hash 48B (SHA3-384)
- 为 Address 类型补充 to_binary_string / from_binary_string 方法（8组二进制字符串转换）
- 部署到主网 9548 端口，systemd 服务已启用
- 创世宪法哈希: fcf63b075177c0aca795d08d0b9c4f5622ee644f957e7b9ee93798b701cc9a657bdf0b9d2f4299c48271588dbb598bdb
- Chain ID: 5132611
