feat: 主网模块集成 + 彻底去除以太坊技术栈残留 

本次提交完成以下工作：

1. 去除以太坊技术栈残留（FIX-ETH-001）
   - nac-cbpp: 重写 consensus.rs/vote.rs/validator.rs
     * BFT Prevote/Precommit → CBPP 宪法收据（CR）验证
     * Validator/voting_power → 区块生产者（CBP）/DID 身份
     * SHA256 → SHA3-384（48字节）
     * Gas → ComplianceFee（合规费）
   - nac-cli: 移除 secp256k1，改为 BLS 简化实现
   - nac-upgrade-framework: 投票机制 → 宪法授权审批
   - nac-udm: 修正 validator/stake 描述为 CBP/DID

2. 主网模块集成（INT-001）
   - nac-api-server v3.0.0: 统一代理所有主网微服务
     * /api/v1/{module}/... 统一入口
     * 支持 NVM/ACC/Charter/GNACS/CNNL/Exchange/Wallet/Onboarding
     * 聚合健康检查 /api/v1/health/all
   - 修复 Exchange/GNACS/CNNL 代理路径映射

3. 代码质量
   - nac-asset-onboarding: 修复所有编译错误（0错误0警告）
   - nac-sdk: 添加 NacLensClient stub
   - 旧版 wallet 模块归档至 _archive/wallet_legacy_v1/

编译状态: 16/16 核心 crate 全部通过（0错误0警告）
集成测试: 8/8 模块通过 API Server 统一入口互通

//! - 哈希算法：SHA3-384（48 字节），不是以太坊的 Keccak-256（32 字节）
//! - 地址格式：32 字节，不是以太坊的 20 字节
//! - 区块大小：流体区块模型（FBM），动态调整，无固定大小
//! - 无 Gas 机制：NAC 使用合规费（Compliance Fee）而非 Gas
//! - 无 Nonce 挖矿字段：CBPP 不使用 PoW

//! 宪政区块生产协议（CBPP - Constitutional Block Production Protocol）
//!
//! NAC公链的共识机制，结合DPoS和BFT的优点
//!
//! NAC 公链的原生共识机制。CBPP 是一套基于宪法规则驱动的区块生产协议，
//! 与以太坊及其他公链的共识机制有根本性区别：
//!
//! # CBPP 核心原则
//!
//! ## 1. 参与即共识
//! 节点遵守宪法规则的行为本身就是共识，无需额外投票或协商。
//! 与 BFT（Tendermint）的 2/3 投票确认机制完全不同。
//!
//! ## 2. 宪法收据（CR）驱动
//! 每笔交易必须由宪法执行引擎（CEE）签发宪法收据（CR）才能上链。
//! 节点只需验证 CR 的有效性（签名 + 时间窗口 + 宪法哈希），无需协商。
//!
//! ## 3. 开放生产网络（OPN）
//! 任何满足 DID+KYC 要求的节点都可以成为区块生产者（CBP），
//! 无需质押代币（不是 PoS），无需算力竞争（不是 PoW）。
//!
//! ## 4. 流体区块模型（FBM）
//! 区块大小和生成频率由实时交易负载动态决定，无固定大小和间隔。
//!
//! ## 5. 收据权重分叉选择
//! 分叉时选择从创世块到当前区块累计 CR 权重最高的链，
//! 不使用算力（PoW）、质押（PoS）或投票（BFT）。
//!
//! # 与其他共识机制的对比
//!
//! | 维度 | CBPP | PoW | PoS | BFT |
//! |------|------|-----|-----|-----|
//! | 共识方式 | CR 验证 | 算力竞争 | 质押投票 | 2/3 投票 |
//! | 参与条件 | DID+KYC | 算力 | 质押代币 | 许可节点 |
//! | 分叉选择 | CR 权重累计 | 最长链 | 最重链 | 不分叉 |
//! | 出块触发 | 交易驱动（FBM） | 算力竞争 | 轮换/随机 | 领导者选举 |
