Krzysztof kuhy Rudnicki 42007d56e4 PORR runs in 28s, and three checks so the next pass cannot repeat my mistakes
PORR was the last course whose `run` did not work. Four measurements, not
guesses, explain why -- and none of them is the matrix size everyone assumes:

  ProcessingType.PROCESSES   20.9s at n=2, 32.8s at n=5, 78.2s at n=10. That
                             is process-pool setup PER TEST, and it grows.
  matrix_type poli3          densifies a sparse .mat into a 2.3 GB npz cache
                             (nemeth12: 723 MB) -- over the 2G ceiling before
                             any solving happens.
  n=10000                    800 MB matrix, and np.linalg.solve wants a copy.
  n=5000                     spd_5000.npz was a Git LFS pointer whose object
                             404s on GitHub, so it regenerates from scratch.

Remove those and what is left still exercises the whole Richardson
implementation at every size that fits: 18 tests, 28 seconds through the
harness, exit 0. The submitted parameter set is one documented environment
variable away. `main.py` now propagates pytest's status (verified: exit 5 when
nothing is collected) -- it discarded it before, so `run` could not tell a
passing suite from a failing one.

The rest of this commit is scripts/check_refactor_safety.py, which exists
because three regressions got past both ruff and a smoke run during this
campaign, and I would rather they could not get past the next one:

  --signatures      diffs two trees function by function, parameter by
                    parameter, default by default. This is what found the 22
                    EARIN functions whose defaults an annotation pass silently
                    dropped.
  --logging         a module with a __main__ guard that logs at INFO must call
                    basicConfig, or it prints nothing at all. Found two more
                    in PORR just now.
  --print-keywords  refuses to let an automated rewrite near print(x, end="")
                    or print(x, file=sys.stderr); losing those turns a
                    rendered board into one glyph per line, or silently moves
                    error output onto stdout.

All three pass on the whole archive. Also in here: 12 latent TypeErrors mypy
found in EARIN that ruff could not -- call sites still passing positionally to
parameters this campaign had made keyword-only, plus one caller of a function
whose argument I had removed. Every one would have raised at runtime.
