classSystemRegistry

@codexo/exojs / core / stable

Ordered registry of per-frame Systems, shared by Scene (as `scene.systems`) and `Application` (as `app.systems`). Systems tick once per frame in ascending `order` (ties keep insertion order) and are destroyed in reverse registration order when the registry is destroyed. Structural mutations made from inside a system's `update()` (a system adding or removing another, or itself) are deferred until the tick completes, so the iteration is never invalidated mid-frame.
