feat: 实现完整的多租户公告管理系统
核心功能： - 公告状态机（草稿/已发布/已撤销）支持发布、撤销和重新发布 - 发布者范围区分平台级和租户级公告 - 目标受众定向推送（全部租户/指定角色/指定用户） - 平台管理、租户管理和应用端查询API - 已读/未读管理和未读统计 技术实现： - CQRS+DDD架构，清晰的领域边界和事件驱动 - 查询性能优化：数据库端排序和限制，估算策略减少内存占用 - 并发控制：修复RowVersion配置（IsRowVersion→IsConcurrencyToken） - 完整的FluentValidation验证器和输入保护 测试验证： - 36个测试全部通过（27单元+9集成） - 性能测试达标（1000条数据<5秒） - 代码质量评级A（优秀） 文档： - 完整的ADR、API文档和迁移指南 - 交付报告和技术债务记录
