Stale GPU handle

A buffer, image, pipeline or acceleration-structure handle was used after its resource was destroyed, or with a device it does not belong to. Handles are generation-checked, so the call failed instead of touching freed memory.

#Common causes

• A system kept a handle across a frame in which the resource was destroyed (a reload, a resize, an asset swap).
• A handle from one ara-gpu device was used with another (several viewports or a recreated device).
• A double destroy: the second call sees the bumped generation.

#Fixes

• Re-fetch handles from their owner after asset reloads and swapchain resizes instead of caching them.

• Destroy resources through their owner only, once, and drop the handle with them.
