UNITY-EXPLORER-NT8 (824 evts/2 users): EcsSystemException [GliderPropControllerSystem]. The glider prop View is parented to the avatar transform; when the avatar GameObject is torn down by Unity, the child View is destroyed while the ECS GliderProp component still references it. CleanUpDestroyedAvatarsProp then dereferences the destroyed View (PrepareForNextActivation / .gameObject), throwing out of Update. Early-return on Unity-null View (overloaded ==), matching the codebase's SafeDestroy/null-guard idiom. Unverified (no Unity build).

fixes #8064


Supersedes #9405: moved from the fork into the org repo so CI workflows receive repository secrets (fork PRs do not).
