Topology (entangling-layer patterns)
Named entangling-layer connectivity patterns for variational circuits (linear, circular,
full, star, brick) -- the same role Qiskit's TwoLocal(entanglement=...) or PennyLane's
qml.broadcast(pattern=...) play, returning a plain gate-tuple list ready for run_circuit.

See also: ghz_state builds its CX chain with entangling_layer(pattern='linear')
directly. This package's DenseSVSimulator has no notion of hardware connectivity at all (any
two qubits can always interact) -- these patterns are an ansatz-design convenience, not a
constraint the simulator enforces.
