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.

d349b93d1d Add Copilot skill architecture with 10 skills, 2 agents, and shared infra 
Introduce .github/skills/ with solve, prove, optimize, simplify,
encode, explain, benchmark, memory-safety, static-analysis, and
deeptest skills. Each skill follows a SKILL.md + scripts/ pattern
with Python scripts backed by a shared SQLite logging library
(z3db.py). Two orchestrator agents (z3-solver, z3-verifier) route
requests to the appropriate skills.
