Syncing the same multi-page video twice in quick succession can start overlapping sync work, because the lock is released before the work finishes. Playback tracing can also attribute events to the wrong playback during rapid track switching, which affects telemetry only. The lock release should be fixed before merge.

保留 getPageList 的实例绑定。
favorite.ts 的 Line 336–337 将 api.getPageList 作为独立函数传给 fetchPageLists。后者在 Line 61 直接调用该函数。现在方法访问 this.client，此调用会因 this 为 undefined 而抛出 TypeError。
当用户开启分 P 展开，且存在需要查询分 P 的视频时，同步会异常退出，无法进入持久化阶段。请将 getPageList 改为绑定实例的箭头函数，或在传递回调时使用 (params) => api.getPageList(params)。

在定义 getPageList 的位置保留其实例绑定，使 favorite.ts 将其作为独立回调传给 fetchPageLists 后仍能访问 this.client；可将 getPageList 改为绑定实例的箭头函数，或在传递时用包装回调调用 api.getPageList。

检查 `favorite.ts` 中 `traceSpan` 对 `fn(withTraceDeps(deps, span))` 的返回值，并在返回 `Result` 为 `Err` 时于 span 结束前标记错误；同时确保 `facade.ts` 中 `traceOperation` 将 `runFavoriteSync` 返回的 `Err` 传播为根 transaction 的错误状态。保留现有的 `Result` 返回契约，并优先复用支持 `Result` 的追踪包装器或既有错误标记机制。

Review comment at @apps/mobile/src/lib/player/playbackSession.ts around lines 119 - 120:
调整 playbackSession 中由 options.playNow、options.playNext 和 options.startFromKey 推导 willPlay 的逻辑：分别判断本次操作是否会开始播放，以及 JS 是否需要调用 Orpheus.play()。有效 startFromKey 且 playNext 为 false 时，即使无需调用 Orpheus.play()，也要创建 playback.start span 并注入原生追踪上下文；保留现有 JS 播放调用条件。

校验事件归属后再取走 pending span。
快速从 A 切换到 B 时，如果 A 的 headless 事件在 B 创建 pending span 后才到达，这里会取走并结束 B 的 span，并把 playback.first_track_id 写成 A。B 自己的事件随后无法完成对应 span。原生事件通过独立的 headless service 传递，当前消费者没有关联校验。(raw.githubusercontent.com)

更新 PlayerSideEffects 中调用 takePendingPlaybackSpan 的事件处理逻辑及 pending span 状态：保存目标曲目或播放请求标识，并先将到达事件与该标识匹配，只有匹配时才取走并清空 pending span；不匹配的旧事件不得消费新请求的 span，也不得据此写入 playback.first_track_id。

更新创建 transaction 的逻辑，使用 Sentry 8.62.0 提供的 Sentry.continueTrace continuation API 替代不存在的 TransactionContext.fromSentryTrace。处理 continueTrace 的可空结果后，再设置 transaction 名称和 operation 并启动 transaction；保留现有的错误处理行为。

结果是，同一曲目每次获得新的 st 后都会使用不同缓存 key，无法命中既有下载或播放缓存；离线启动已缓存曲目也会进入网络解析并失败。默认 key 使用已有 DataSpec.key，否则使用完整 URI。(raw.githubusercontent.com)
请为两层 CacheDataSource.Factory 配置一致的稳定 key 规则，在缓存查找前剥离 st，同时保留 URI 中供 resolver 使用的追踪上下文。

在 getPlayerDataSourceFactory 中，为下载缓存和 LRU 缓存配置一致的稳定缓存 key 规则：优先沿用已有的 DataSpec.key，否则以移除 st 参数后的 URI 作为缓存 key。确保规则在缓存查找前生效，同时不要修改传给 resolver 的原始 URI，以保留其追踪上下文。

背景
此前 service 层直接调用
Sentry.startSpan，但没有业务根 span：方案：显式传递 parent
Sentry.startSpan的隐式嵌套在 RN 上不可靠：await后 active span 不可靠，子 span 可能丢失 parent 或挂错流程；parentSpanIsAlwaysRootSpan，隐式嵌套会被拍平到根 span。因此新增
apps/mobile/src/lib/tracing.ts，span 不进入全局 scope，由调用方显式传递 parent：startOperation/traceOperation/traceOperationResult：业务根 transaction，每次生成新的 trace IDtraceSpan/traceResult：在给定 parent 下创建子 span；没有 parent 时不产生 span（不再有孤儿 transaction）Err和抛出的异常都会把 span 标记为失败db.system.name/db.operation.name/db.collection.nameapi client 和各 service 通过
withTrace(span)获得挂在指定 parent 下的实例。业务 transaction
playback.startonTrackStarted；覆盖startFromKey点歌路径。快速切歌标记playback.cancelled，入队失败 /onPlayerError标记失败，30s 未起播标记deadline_exceededsync.bilibili_favoritesync.bilibili_collection/sync.bilibili_series/sync.bilibili_multi_pagelyrics.smart_fetchupdate.checkB 站 API 的 HTTP span 只记录
server.address+url.path，不记录 query（wbi 签名、csrf 等不进入遥测）。issue 关联 trace
markSpanError会记录错误最先失败的 span，beforeSend沿cause链反查并写入contexts.trace。即使错误在 trace 结束后才由 React Query 等上层上报，issue 也能跳转到对应 trace。采样
