Etapa G: libs C base libffi + sqlite + readline (corpus 235→238)

libffi 3.5.2 (libffi.a), sqlite 3.53.2 (libsqlite3.a, FTS3/4/5+rtree+threadsafe),
readline 8.3 (libreadline.a+libhistory.a, vs ncurses/libtinfo del corpus).
Alto unlock: sqlite destraba atuin y la cola DB; libffi el mundo python/-sys.
