Second step towards loading MapLibre on demand: everything that touches it now lives in one framework, so that framework can later be left unlinked. The interactive map view, its annotation view and the coordinate animator move into MapLibreShim, which reaches the app through MapLibreShimProtocol. The app side keeps its MapLibreMapView call site and becomes a thin wrapper that builds a MapViewConfiguration, passing the app-only pieces (map style URLs, marker views, tint colour) across as closures so the shim needs nothing from the app. LocationAnnotation loses its MapLibre conformance and becomes a plain struct, with the shim mapping it onto its own annotation type. MapLibre's log forwarding moves into the shim as well, since TargetConfiguration can no longer reach it.
