mk_qfnia_preamble invoked lia2card with no params, so the default
max_range=101 was in effect. Any integer variable with a concrete
range hi-lo <= 101 was expanded into that many fresh Booleans plus
a sum-of-ITEs, bloating SAT search alongside the nonlinear structure.
On an observed QF_UFNIA benchmark this drove a 0.2s problem to a 30s
timeout.
Mirror the throttle already applied in mk_preamble_tactic
(qflia_tactic.cpp, commit 99cbfa715): limit lia2card to 0-1 integer
variables and nesting depth 1. Wrap with using_params so the
override survives and_then's downstream updt_params calls (passing
the params to mk_lia2card_tactic alone is overwritten when and_then
re-propagates the ambient params to each child).
