graphics: synchronize host file writes and depth clipping

Map paired PS5 depth-clip state through Vulkan pipeline creation and preserve asymmetric hard failures. Prepare GPU-mapped guest ranges before kernel file reads so buffer, texture, and alias ownership remains coherent. Add focused regression coverage and update the current launch target.
