The fourteenth bounded `VirtualMachine.Step` extraction moved local jumps/calls/returns, value-switch

`engine/Age.Engine/Vm/VirtualMachine.ControlFlow.cs`. The top-level dispatcher retains all labels and aliases

Concrete playthrough blockers may still preempt this bounded maintenance work; the consolidation effort does
not replace Phase B gameplay validation or the open cross-platform gates.
