[pycharm] PY-85729 Fix potential OOM: add cancellation logic for background process observer

The background error process observation logic didn't cancel the coroutines, making them last for way longer than needed. Cancellation logic was added to remedy this.

[pycharm] PY-85729 Fix OOM: Force LazyTree recomposition on tree change

It looks like LazyTree composable hogs memory by keeping track of all the previous trees; this is bad for our use case as any snapshot change to the tree will be saved, causing potential OOM by not freeing the processes. This is fixed by forcing a recomposition on each tree change (via key(tree)).
