refactor: optimize queue job

[GaoFuhong]

Description

主要改动：

1. 【主要】新增 pendingJobs，去重合并同一任务，对同一 id 的重复任务不再追加多条队列项，使用 Map 更新已存在任务的 cb 和 priority。
2. flushJobs() 中在 requestIdleCallback 有 timeRemaining() 时优先使用剩余时间作为预算，否则才用帧预算 frameInterval，把原来的 frameInterval 33 改为 16，更接近 60 fps。
3. scheduleJob() 中增加 requestAnimationFrame，处理 Safari 等环境。

试验对比：

1. 更新节点属性：

不去重（Before）	去重（After）
入队多少就执行多少	同一节点在一个 tick 内做 3 次属性更新，会合并两次，执行数远小于入队数

2. 平移：优先级为 JOB_PRIORITY.PRIOR，直接执行，不受影响

Before	After

Summary of Changes

Hello @GaoFuhong, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly refactors the job queuing mechanism to improve performance and efficiency. By introducing task deduplication, the system avoids redundant processing of identical jobs within a single tick. Furthermore, the scheduling logic has been refined to leverage browser idle time more effectively and to ensure smoother execution across different environments, aiming for a more consistent 60 frames per second experience.

Highlights

• Task Deduplication: Implemented a 'pendingJobs' Map to prevent duplicate tasks with the same ID from being added to the queue. Instead, existing tasks' callbacks and priorities are updated, ensuring only the latest state of a task is processed.
• Optimized Job Flushing: The 'flushJobs' method now intelligently uses 'requestIdleCallback''s 'timeRemaining()' as a budget, falling back to a reduced 'frameInterval' (16ms from 33ms) for more responsive processing and a target closer to 60 frames per second.
• Enhanced Scheduling Compatibility: 'scheduleJob' now includes 'requestAnimationFrame' as an intermediate scheduling mechanism between 'requestIdleCallback' and 'setTimeout', providing better compatibility and performance across various browser environments, including Safari.

Code Review

你好，感谢你对 JobQueue 的优化。这次重构通过引入 pendingJobs 来合并重复任务，显著减少了不必要的队列操作，从性能测试图来看效果很明显。在 flushJobs 中动态调整执行预算，以及在 scheduleJob 中增加 requestAnimationFrame 作为备用方案，都是非常棒的改进，提升了渲染的流畅性和环境兼容性。

代码整体质量很高，我只发现了一些小问题，主要是在 cancelScheduleJob 中有一个潜在的逻辑 bug，以及一处可以简化的代码。具体细节请看我的评论。

做得很好！

这类代码人工加单测，每个 pr 都注意加单测。之前批量 ai 加单测，其实单测质量、有效性不高的。
