v8.0.1

Fixed

• optimize_team pair recommendations split the first reason into single
  characters. The two-slot path spread a string (...condition ? … : …) where
  it meant to place one reason element, so reasons[0] became one character per
  entry and the output rendered a letter per line. The stray spread is removed;
  the smoke suite now asserts every reason is a multi-character string so the
  regression cannot return.
