back

Pops the current screen. If the back stack contains only the root screen, showExitDialog is invoked instead.

Do not remove the transition entry from transitionStore here. io.github.alimsrepo.navease.internal.navigation.ui.NavDisplay reads popTransitionSpec after the backstack mutation, so the entry must still be present when the pop animation starts. Stale entries are evicted lazily on the next navigate call.
