Stacked on #45. Merge adjacent same-direction overflow-staging transfers when their sources and destinations are physically contiguous, without changing expert/remap order. Validation: four-sample cache48 prefill +0.33% at 8K and +0.12% at 32K with equal VRAM; deterministic 8K/32K JSON and two-corpus PPL match the direct parent exactly; focused two-slab D2D/H2D coverage and Compute Sanitizer pass.
