- 抢购内核改为"每账号独立重试循环"，移除轮次屏障：旧实现在 3 个中签账号卡住 60 秒支付退避时，另外 31 个账号空转 39 秒，还出现过"某一轮只跑 1 个账号、其余整轮没被尝试" - 锁单退避改为读取配置的"重试间隔策略"（同一账号连续失败成倍放大，封顶 5 秒）， 删掉硬编码 30 秒退避与"只重试一次" - 锁单失败不再提前停止：限流（活动火爆/网络繁忙）继续重试；售罄也继续降频探测 （别人锁单后支付失败或锁单过期，库存会回流），只在窗口结束时按售罄/限流/普通失败分类上报 - 支付重试按斗鱼错误码决策：1644430001/1644400002/1644400014 视为"订单已受理、结果未定" 并快重试（300ms 起），取代按文案把"订单操作进行中"误判成频控的 60 秒退避； 不再设次数上限，只受 120 秒预算与锁单过期约束，超出预算如实报"支付结果未知" - 已锁订单在 75 秒窗口结束后仍会支付完，不再受窗口约束 - 多实例：为每个实例分配独占的 WebView2 用户数据目录。Wails 默认所有实例共用 %APPDATA%\<可执行文件名>，而一个数据目录只能有一个浏览器进程，导致偶发开不出新实例、 必须全部关掉重开；实例占位因此提前到 wails.Run 之前完成 - 多实例：占位失败不再静默退回默认目录（会让两个进程共享 accounts.txt/config.json、 同秒启动还会写同一个日志文件），改为进程唯一的临时实例目录并记录降级原因 - 多实例：单个槽位锁被瞬时占用（杀软/索引器）时短暂重试，仍失败则继续试下一个槽位 而不是整个分配失败；日志文件改为独占创建，同秒启动自动追加 -2/-3 后缀 - 新增 %LOCALAPPDATA%\douyu-go\startup.log，记录每次启动与失败原因， 便于排查"窗口起不来"这类连应用日志都不会生成的问题 - 修复预热缓存日志每个账号打两遍、"账号尝试"计数误导（改为真实锁单/支付/直接兑换次数） - 修复前端把含"成功"字样的失败文案显示成抢到（改为只认"成功|"前缀） - 修复 jitterDuration 在基准小于 10ms 时 rand.Int63n(0) 会 panic 的隐患 - 设置页文案与作用域同步：重试间隔策略明确作用于锁单重试、"尝试包数"明确仅用于和平小店
