docs: 06-区块链开发指南 v3.0 量产版 — 去除全部MVP/阶段性限制
变更明细： - 链设计参数：共识机制从"初期平台运营"改为"平台+合格机构验证节点" - 节点运营：去掉"未来开放"，直接定义多机构验证节点架构 - CouponFactory：移除Utility-only硬编码限制，开放Utility+Securities双轨制 - Securities Track增加合格投资者验证+Broker-Dealer合规检查 - 新增第11节"多机构验证节点架构"： - 4类节点（创世验证/机构验证/监管观察/全节点）准入条件 - 生产验证节点CometBFT共识配置（出块≤1s） - 部署拓扑（Genex x3 + 机构 x4+ + 监管 x3） - GNX代币：去掉"待法律意见书后开放"措辞，改为"需合规审批" - 代币分配去掉"预留设计"标签 - CBS资产证券化：从Phase 4接口预留升级为完整合约实现 - createPool（券收益流打包） - purchaseShares（合格投资者份额认购） - setCreditRating（链下评级机构写入） - distributeYield（到期收益按份额分配） - Gas策略保持不变（前期补贴+未来可通过Governance调整） - 章节重新编号（11→21共21节） Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
