Add --offload-towers: place multimodal tower weights in pinned host memory and bulk-copy each unit to the GPU only during its forward, keeping towers out of VRAM between encodes. Unlike UVA zero-copy, whole-tensor H2D transfers avoid re-reading operand tiles over PCIe inside the GEMM inner loop. Tower streaming is independent of layer group scheduling, so group_size may be 0 for tower-only offload. Co-authored-by: Hinata <hinata@idihore.id> Signed-off-by: MOVZX <movzx@yahoo.com>
