zerosaturation e1326acaf9 fix(backend): service stability — bcrypt off-txn / login anti-enum / MQ stub / aiChat / event reliability / gateway aggregate (batch 3) 
- 3.1 bcrypt 移出事务 (Register): repository.HashPassword 前移到 db.Transaction 之前,消除连接池占用。
- 3.2 Login 消除用户枚举 + 限流 + timing 抹平: pkg/errors 加 ErrInvalidCredential
  /ErrTooManyLoginAttempts; 用户不存在/密码错/密码空 三路径统一返回同一错误;
  mobile 5次/ip 20次 per 15min 限流 (Redis, fail-open 降级); user-not-found 走
  dummy bcrypt 抹平 ~100ms 时序差,完全消除枚举侧信道;空密码分支已核实无时序 leak。
- 3.3 MQ streams adapter 停用 → stub: 0 业务调用方, 新 stub EventProducer.Publish no-op;
  pkg/mq/mq.go Init 不再装配 streams; 全仓 grep 验证 11 处硬编码
  'gallery'/'default' 集中到 pkg/queue/consts (值不变, 仅消漂移)。
- 3.5 JWT 密钥治理: pkg/jwt MustInit fail-fast + atomic.Value (见上一个 commit 293c7b1)。
- 3.6 aiChat 健壮性: SaveContext 用 persona.ID(非 req.PersonaId); Redis/memory 错误
  记 WARN 不静默; Dify err 映射稳定用户文案,原始 err 仅服务端日志。
- 3.7 statistic.Client 重构: TrackEvent 改 buffered channel (cap 1024) + dispatchLoop
  worker; 失败 ERROR 日志带字段; drop 记 WARN; Close 可重复调用。
- 3.8 网关聚合: StarCache (60s TTL, singleflight) 替换 5+ 处 GetFanIdentities 链式调用;
  DeleteAccount 改网关直调 userService.DeleteAccount(避免改 hand-written triple.go
  风险,见报告 §5 proto 风险复盘); 铸造双写改异步 channel+consumer (3 retry)。
- 大量单测: 各子项 TDD (RED→GREEN), 关键并发 race_test (50 goroutine)。
