b8d6952e9e Enable som (sum of monomials) in optimizer simplification 
The optimizer's simplification pass did not expand products of sums
into sum-of-monomials form. This caused mathematically equivalent
expressions like (5-x)^2 vs (x-5)^2 to simplify into different
internal forms, where the former produced nested multiplies
(+ 5.0 (* -1.0 x)) that led to harder purification constraints
and solver timeouts.

Enabling som=true in the first simplification tactic normalizes
polynomial objectives into canonical monomial form, making the
optimizer robust to operand ordering.

ce7c7f458e Add max_rev test: BNH with reversed argument order in f1/f2 
Same as test_bnh_optimize but constructs f1 and f2 with reversed
parameter order in mk_add, mk_mul, mk_sub calls. Exposes optimizer
sensitivity to expression structure.

8e47c0d842 Fixed the assertion violation in mpz.cpp:602 when running with -tr:arith. 
**Root cause**: `vector::resize(SZ s, Args args...)` in `src/util/vector.h` took `args` by value and used `std::forward<Args>(args)` in a loop. The first iteration moved from `args`, leaving all subsequent elements with a moved-from state (`rational{0/0}` instead of
`rational{0/1}`). This corrupted the coefficient vector in the pretty printer, causing a division-by-zero assertion when multiplying.

**Fix**: Changed `resize` to take `Args const& args` and copy-construct each element instead of forwarding/moving.
