Adds VITE_DECNET_DEVELOPER build-time gate: when unset, the isDeveloperMode() helper collapses to a constant false and Vite tree-shakes both the lazy import and the conditional <Route> out of the prod bundle. ThemeLab is currently a header stub; subsequent tasks fill it with the design-system primitive zoo plus a Dark/Light toggle for live token tuning. Route is intentionally absent from ROUTE_LABELS / sidebar — direct URL only.
