fix(scheduler): improve error recovery

[yangmingshan]

This PR improves the error recovery on jobs flush, and with two other changes:

1. recursive post jobs can't be re-queued by other jobs.
2. reset currentFlushPromise only when no jobs are left to flush, to avoid unnecessary microtask.

There are two possible issues:

1. jobs may left on queue when flushPreFlushCbs or flushPostFlushCbs errors.
2. flushPreFlushCbs does not check the DISPOSED flag, not sure if it's intentional.

This PR is based on minor, let me know if I should change to main.

Thanks for the PR. LGTM.

jobs may left on queue when flushPreFlushCbs or flushPostFlushCbs errors.

fixed via 87742a8

flushPreFlushCbs does not check the DISPOSED flag, not sure if it's intentional.

flushPreFlushCbs() does not check for DISPOSED, mainly because there is no built-in path in the current runtime to mark pre-watcher jobs with this flag.

pre-jobs actually have only one source: watch(..., { flush: 'pre' }), which is enqueued via queueJob(job, ..., true). When a component is unmounted, scope.stop() is called on its scope first. Even if a watch job remains in the queue after the effect is stopped, its execution becomes a no-op because this.dirty is no longer truthy. It is bypassed not by checking DISPOSED, but because the effect itself has been invalidated.
