Anade 9 primitivas reutilizables al registry C++ que replican el comportamiento de los componentes correspondientes de @fn_library / Mantine v9, todas estilizadas con tokens_cpp_core (colores Mantine dark + indigo): - button_cpp_core (component, pure) variantes primary/secondary/subtle/danger + sm/md/lg - icon_button_cpp_core (component, pure) cuadrado 28x28 con glyph centrado + tooltip - toolbar_cpp_core (component, pure) grupo horizontal de acciones con separadores - modal_dialog_cpp_core (component, pure) popup modal centrada + close con Escape - text_input_cpp_core (component, impure) InputText con label muted + placeholder - select_cpp_core (component, impure) dropdown con label + opcion '(none)' opcional - toast_cpp_core (component, impure) notificaciones efimeras + inbox con badge - tree_view_cpp_core (component, impure) jerarquia low-level con tree_node_clicked helper - process_runner_cpp_core (component, impure) tarea en std::thread + spinner inline Cada primitiva tiene su .md con frontmatter completo (params/output) y se indexa via fn index. Son la base del primitives_gallery y de cualquier app fn_ui futura.
