This PR introduces finer-grained scheduling priorities for the Yazi task system, supplementing and enhancing the existing micro and macro tasks.
Previously, Yazi categorized tasks requiring quick responsiveness as micro tasks; and larger, heavier tasks capable of running in the background as macro tasks. However, they had to queue for execution, leading to head-of-line blocking when significant sudden requests occurred.
Now, 3 priority levels (low, normal, high) have been introduced, for both micro and macro tasks. This finer granularity in task handling, and the introduction of new concurrency, allow high-priority tasks to preempt more resources. This will make Yazi more responsive.
The more important thing is that it also covers the Yazi plugin system, which will allow users to allocate different priority levels on demand for their preloader, previewer, and functional plugins.
