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.

9d674404c8 Add action/expectation/result structure to all skill definitions 
Each step in every SKILL.md now carries labeled Action, Expectation,
and Result blocks so the agent can mechanically execute, verify, and
branch at each stage. Format chosen after comparing three variants
(indented blocks, inline keywords, tables) on a prove-validity
simulation; indented blocks scored highest on routing completeness
and checkability.
