[Fix] (DirectVulkan): make texture/renderbuffer GC reach every dead resource - name-deleted textures register via weak_from_this so first-sync-after-delete can no longer orphan a TextureResource, an orphan sweep makes GC authoritative over the resource map, dead-texture pruning moves to a frame-boundary gate (64 frames) so churn through clears/readbacks reclaims without draws, and dead renderbuffers age past frames-in-flight before their VkImage/view is destroyed instead of leaking until shutdown (or being freed while in flight)
