chore(docs): docs/ 目录全面重新编号 + 重组

**重构前**（旧编号 02-11）：
- docs/02-产品需求/      → 00 产品规划/PRD
- docs/03-技术架构/      → 01-05 子目录散落
- docs/04-原型设计/      → 01-02 产品设计（HTML 原型）
- docs/05-原型设计/      → screens/
- docs/06-测试素材/      → 02-E2E / 03-功能 / 04-版本测试
- docs/07-项目管理/      → 任务说明书/日报/计划
- docs/08-安全审计/      → 审计报告
- docs/09-堡垒运维/      → toolbox / deploy
- docs/10-项目管理/      → 任务说明书（重复）
- docs/11-历史归档/      → deploy-nas-archived

**重构后**（新编号 00-07，语义化）：
- docs/00-产品开发流程与文档管理规范.md
- docs/00-版本迭代总览.md
- docs/01-产品文档/      （PRD/原型/认证/会话/AI 服务/坐席/集成）
- docs/02-技术文档/      （技术方案/架构图/重构记录/前端改造/实现配置）
- docs/03-测试文档/      （E2E/功能用例/版本报告/缺陷单）
- docs/04-运维文档/      （部署运维/运维指南）
- docs/05-运营文档/      （品牌推广/用户手册）
- docs/06-安全审计/      （审计报告）
- docs/07-项目管理/      （任务说明书/日报/计划/看板）

**净收益**：
- 目录编号与产品文档管理规范对齐（按文档阶段 01-07 编号）
- 消除 02-产品需求 与 10-项目管理 的编号重叠
- 子目录按文档类型分组（如 01-产品文档/00-产品规划、01-产品文档/01-认证与登录）
- 把运维/安全/项目管理从 0X 散落改为 04/06/07
