feat(acc): 补全 L2 charter-std 和 L3 nac-sdk 全部 ACC 协议族接口

charter-std/acc 新增 11 个 .ch 文件:
  acc1155.ch, acc_rwa.ch, acc_compliance.ch, acc_valuation.ch,
  acc_custody.ch, acc_collateral.ch, acc_redemption.ch, acc_insurance.ch,
  acc_governance.ch, acc_xtzh.ch, acc_reserve.ch

nac-sdk/protocols 新增 10 个 .rs 接口文件:
  acc_rwa.rs, acc_compliance.rs, acc_valuation.rs, acc_custody.rs,
  acc_collateral.rs, acc_redemption.rs, acc_insurance.rs, acc_governance.rs,
  acc_xtzh.rs, acc_reserve.rs

更新 nac-sdk/protocols/mod.rs 导出所有 22 个协议

所有协议严格使用 NAC 原生类型系统（Address 32字节，Hash 48字节 SHA3-384）

 # NAC SDK Protocols Module
+NAC SDK 协议模块，提供完整 ACC 协议族的接口。
+所有协议均为 NAC 原生实现，通过 NRPC4.0 与链交互。
 
-NAC SDK的协议模块，提供ACC协议族的接口。
+## 完整 ACC 协议族（22个协议）
 
-## ACC协议族
+### 基础代币协议（4个）
+- `ACC-20` - 可替代代币标准
+- `ACC-20 Enhanced` - 增强可替代代币（含GNACS）
+- `ACC-721` - 不可替代代币标准（含AssetDNA）
+- `ACC-1155` - 多代币标准
 
-### 基础代币协议
+### RWA 专用协议族（8个）
-- `ACC20` - 可替代代币协议
+- `ACC-RWA` - 真实世界资产注册与转移协议
-- `ACC721` - 唯一资产证书协议 ✅
+- `ACC-Compliance` - 七层合规验证协议
-- `ACC1155` - 多代币协议 ✅
+- `ACC-Valuation` - AI 驱动资产估值协议（CNNL 接口）
+- `ACC-Custody` - 资产托管协议
+- `ACC-Collateral` - 抵押协议（XTZH 计价）
+- `ACC-Redemption` - 赎回协议
+- `ACC-Insurance` - 资产保险协议
+- `ACC-Governance` - 治理协议（提案/投票/执行）
 
-### RWA专用协议（待实现）
+### 稳定币与储备协议（2个）
-- `ACCRWA` - RWA资产协议
+- `ACC-XTZH` - XTZH 稳定币协议（SDR锚定+黄金储备）
-- `ACCCompliance` - 合规协议
+- `ACC-Reserve` - 多资产储备协议
-- `ACCValuation` - 估值协议
-- `ACCCustody` - 托管协议
-- `ACCCollateral` - 抵押协议
-- `ACCRedemption` - 赎回协议
-- `ACCInsurance` - 保险协议
 
-### 治理与稳定币协议（待实现）
+### 证券代币协议族（5个）
-- `ACCGovernance` - 治理协议
+- `ACC-1410` - 分区代币协议（股权分区/分红/投票）
-- `ACCXTZH` - XTZH稳定币协议
+- `ACC-1400` - 证券代币协议（合规+股息+投票）
-- `ACCReserve` - 储备协议
+- `ACC-1594` - 收益分配协议
+- `ACC-1643` - 文档管理协议（链上文档版本控制）
+- `ACC-1644` - 监管控制协议（冻结/强制转移/监管接管）
 
-## NAC原生设计
+### 兼容层（1个）
-
+- `ACC-20C` - 合规兼容层
-- ✅ 使用NAC原生术语（Asset Holdings而非Balance）
-- ✅ 使用证书地址（Certificate Address）而非合约地址
-- ✅ 使用资产转移（Transfer Asset）而非转账
-- ✅ 内置合规验证
 
+## NAC 原生设计原则
+- ✅ Address 32字节，Hash 48字节（SHA3-384）
+- ✅ 使用 `holdings` 而非 `balance`
+- ✅ 使用 `TransactionContext` 而非 `msg.sender`
+- ✅ 使用 `ConstitutionalReceipt` 作为操作宪法凭证
+- ✅ 完全规避以太坊模式
