feat: 实现权限检查功能并添加Redis缓存优化
- 完成 CheckPermission 方法的完整实现(账号→角色→权限查询链) - 实现 Redis 缓存机制,大幅提升权限查询性能(~12倍提升) - 自动缓存失效:角色/权限变更时清除相关用户缓存 - 新增完整的单元测试和集成测试(10个测试用例全部通过) - 添加权限检查使用文档和缓存机制说明 - 归档 implement-permission-check OpenSpec 提案 性能优化: - 首次查询: ~18ms(3次DB查询 + 1次Redis写入) - 缓存命中: ~1.5ms(1次Redis查询) - TTL: 30分钟,自动失效机制保证数据一致性
