新增 UMQ (User Message Queue) 双模式支持: - serialize: 账号级分布式串行锁 + RPM 自适应延迟（严格限流） - throttle: 仅 RPM 自适应前置延迟，不阻塞并发（软性限速） 后端: - config: 新增 Mode 字段，保留 Enabled 向后兼容 - service: 新增 UserMessageQueueService（Lua 锁/延迟算法/清理 worker） - repository: 新增 UserMsgQueueCache（Redis Lua acquire/release/force-release） - handler: 新增 UserMsgQueueHelper（SSE ping + 等待循环 + throttle） - gateway: 按 mode 分支集成 serialize/throttle 逻辑 - lint: 修复 gofmt rewrite rules、errcheck 类型断言、staticcheck QF1012 前端: - 三态选择器 UI（关闭/软性限速/串行队列）替代 toggle 开关 - BulkEdit 支持 null 语义（不修改） - i18n 中英文文案 通过 6 轮专家评审（42 次 review）、golangci-lint、单元测试、集成测试。
