Interface: AngularAppStability

Defined in: angular-core/dist/index.d.mts:15

The minimal stability contract AngularInteractor settles against, structurally satisfied by Angular's ApplicationRef (Angular 20+).

Kept structural on purpose: the interactor itself has no dependency on @angular/core, and ApplicationRef.whenStable() already abstracts over zone.js vs. zoneless change detection — it resolves once change detection is idle in either mode.
