feat(cpp/core): logger + log_window + selectable_text widgets

Browse Source 
Logger global thread-safe con ring buffer in-memory de 2000 entradas + escritura
opcional a archivo. log_window flotante consume el ring buffer con filtros por
nivel, busqueda y autoscroll; se abre desde Settings -> Logs en la menubar.
selectable_text cubre el patron drag-to-select + Ctrl+C en cualquier ventana.

app_menubar y framework run_app integran log_window_render() en el frame loop.
