Re-open progressive LOD ladders retired by the consecutive-failure cap.
Whether any failure is worth an automatic retry — a transient loader cause
still under the attempt cap, or a deferred LOD branch latched on an archive
fault. Gating on this keeps deterministic ordinary failures quiet while an
online transition can re-open archive-backed lazy work.
deferred: true ⇒ a main update held the lock and NOTHING was retried.

Narrow view of the SceneLoader the online-retry listener needs. Matches
SceneLoader.hasFailures/retryAllFailedLoadersstructurally so the lifecycle layer doesn't import the loader class.
