Introduce an immutable register topology for units, subregisters, classes, banks, and preserved masks. Bind instruction descriptors to this topology through TargetDescription so builders, cloning, and verification share one target-aware contract. Add the test-only TestTarget model and positive and negative target fact coverage.

Deep-clone the live MachineIR graph with deterministic identity maps while rebuilding CFG, def-use, ties, register configuration, and memory operand ownership. Verify both source and destination and omit detached arena history.
