fix: derived atom is not recomputed after its dependencies changed #2906 #2907

#2906

Summary

When a writable atom sets two different atoms, and another atom indirectly depends on both, the dependent atom may fail to update correctly. Specifically, if the first atom's update results in no actual change, the dependent atom's "dirty bit" gets cleared prematurely. Then, when the second finishRecompute executes, the dependent atom does not recompute because its dirty bit was already cleared.

The proposed solution in this PR is to consolidate all finishRecompute operations into a single process, thereby handling changes to the atom graph in one go.

Thanks for working on it! I'll have a deeper look later.

This does seem to fix the issue, but as you might expected it, I'm not a big fan of this change. (And, I didn't like .D already, so I want to find alternative way in the future.) I'll look for some other solutions. Give me some time.
