[Fix] (DirectVulkan): explicit-LOD blit sampling and present-path hardening - the default-framebuffer blit shader now samples with textureLod 0 (a blit reads exactly the selected level; Adreno 650's implicit-LOD path reads past a single-mip UBWC render target's allocation despite maxLod=0, page-faulting the GPU on MC 26.2's second startup frame once the neighbouring startup staging memory is returned - the invalidated context then failed the next Present submit with EDEADLK/DEVICE_LOST), TransitionToPresent appends the present barrier into the frame's open recording instead of silently dropping it whenever anything was recorded (frames without a default-FBO render pass presented images stuck in their acquired layout), VK_SUBOPTIMAL_KHR acquires are treated as the success they are (image acquired, semaphore signal armed - the early return skipped the fence reset and consumed-flag clear, and callers re-acquired on the same binary semaphore; rebuilds now defer to after the signal is consumed), and validation builds report through VK_EXT_debug_report when VK_EXT_debug_utils is absent instead of aborting instance creation
