Codex WebSocket 的顶层 rate_limits 可能没有来源标识：普通模型请求返回账号额度，Spark 请求则可能重复附加额度。原实现丢弃无来源的顶层窗口，导致普通账号百分比停留在旧值。

现在逐窗口比较同一事件中的顶层与全部附加额度。周期相同且原始 reset_at 或同事件的 reset_after_seconds 对齐（允许 1 秒精度差）时，丢弃顶层副本；确实没有附加窗口，或能在共同时间基准下排除全部附加副本时，按兼容规则归属普通账号。缺少共同基准、周期损坏或副本判断冲突时跳过未知顶层；明确来源仍直接更新。来源比较不使用本地接收时间，已归属额度的展示时间仍支持相对倒计时换算。

每个来源和窗口独立校验：用量损坏不会抹掉用于来源比较的原始时间信息，也不会阻断其他有效窗口。非额度事件先做轻量类型检查，只有额度事件完整解析。整个过程不新增上游请求、历史周期推断、账号缓存或配置；被动更新只更新唯一匹配的已有窗口，不创建或删除窗口。

验证：

• make check，包含全量后端测试、Go vet、编译及前端静态检查与构建。
• 真实普通模型/Spark 样本回放、HTTP/WS 合并对照、跨周期、多个附加来源、空字段、字段损坏、逐窗口去重和复用连接的既有测试通过。
• 新增共同/混合时间基准、字段互换、5 秒延迟、判断冲突回归，以及最终合并保留主账号 93% 且刷新 Spark 的验证。
• 1 MiB 非额度事件本地基准：额外分配由约 5 MiB 降至 32 B/次；类型字段位于首部和尾部均验证，性能数据仅代表该解析函数。
• 用户此前已完成真实账号普通模型/Spark、HTTP/WS、新旧环境 A/B；本轮异常边界使用离线测试，未重复真实账号测试。

📝 Walkthrough

Walkthrough

本次变更调整 Codex WebSocket 额度窗口的解析、保留、匹配和去重规则。解析器现在按窗口周期及重置时间识别顶层账号窗口和附加窗口，并隔离损坏字段。被动快照测试覆盖跨重置周期更新、账户额度保护和窗口来源清理。WebSocket 会话测试覆盖窗口数量变化、复用会话刷新账号百分比，以及 Spark-only 事件。
