Adds the Manifold app (manifold/) — the convertible-mode React front-end on the real NISPS ML+audio engine, served live at meml.lnfinitemonkeys.org/next/. Console chrome trimmed per UI pass: - drop mode label + subtitle from the top-left overlay (keep MEMLNaut wordmark) - remove the composite split preset/ratio readout (top-centre) - remove the OUTPUT corner tag above the bars - remove the A/B compare toggle from the verdict cluster - remove the follow button + input/noise readout (bottom-left) - remove AltitudeNav focus switcher (bottom-right)
