Skip perception checks in Store.publisher

[pyrtsa]

Here's another case of failing perception checks for where TCA, SwiftUI, UIKit, and Combine meet.

Because the store is first accessed inside makeUIView(_:context:), the isSwiftUI() check inside Perception considers it as valid.

But publishers seem to mix very unwell with ObservableState here… Not only should accessing state.count inside the sink { ... } call be free of perception checks: because state is just a struct (mostly!) and as such a snapshot of whatever state the store was in at the time of the publisher emitting a value, accessing its value members shouldn't even touch the observation/perception machinery, I think. Or why should it?

In any case, this is an example of the runtime warnings we started getting when attempting to upgrade to the latest Point-Free library versions.
