1. 去重粒度: 按消息级别去重，通过 SHA256(策略指纹 + consumer + role + content + 图片指纹) 生成唯一键 2. 缓存安全: 策略指纹包含所有影响检测结果的维度，策略变更时自动失效缓存 3. 降级策略: Redis 不可用时自动关闭去重，Lua 脚本失败降级为逐条写入

Summary
为
ai-security-guard插件新增基于 Redis 的消息去重机制，避免对相同内容进行重复的安全检测，提升性能并降低对后端安全检测服务的调用量。核心设计
SHA256(策略指纹 + consumer + role + content + 图片指纹)生成唯一键变更范围
config/config.go- 新增 Redis 去重相关配置lvwang/common/check_helper.go- 新增通用检测辅助工具（含去重逻辑）lvwang/multi_modal_guard/text/openai.go- 多模态检测集成去重lvwang/text_moderation_plus/text/openai.go- 文本审核集成去重utils/utils.go- 新增 SHA256 哈希等工具函数测试覆盖
新增和更新了多个测试文件（+2000 行测试代码）：
