chore: split Topology.Category.Profinite.Nobeling (#23898) The base file is now called Topology.Category.Profinite.Nobeling.Basic, which is separately imported by three new files:

  • .Span for the good products span
  • .ZeroLimit for the zero and limit cases of the ordinal induction
  • .Successor for the successor case of the ordinal induction Then .Induction ties up these files to prove Nöbeling's theorem proper.
