Dashboard Core — Visuals

Every visualization here is native (plain matplotlib/numpy) — no Qiskit anywhere in this module. Aggregates circuit_diagram and state_visuals into the set Composer actually renders.

visuals

Every visualization here is native (plain matplotlib/numpy) -- no Qiskit anywhere in this module. The circuit diagram was already native (dashboard_core.circuit_diagram); histogram/Q-sphere/Bloch spheres are now native too (dashboard_core.state_visuals), replacing qiskit.visualization.{plot_histogram, plot_state_qsphere, plot_bloch_multivector} -- the last Qiskit call sites this dashboard had. Qiskit's macOS instability was never proven scoped to just QuantumCircuit (see circuit_diagram.py's own docstring), so making these three merely "optional" instead of actually removing Qiskit would have left the same open question for a different set of functions; there's no reason left to keep it as a dependency here at all.
