-- Reduce the test set to a small representative subset of MIP instances and
-- lower the per-instance CBC time limit from 2000 s to 120 s so that the
-- pytest suite finishes in a reasonable amount of time during port testing.
-- The full 30-instance list with 2000-second limits is aimed at slow CI runners
-- and includes cases that do not reliably reach optimality with the system
-- CBC within 120 s when run in parallel mode.
