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.

274d64299e Address PR review: add ENSURE checks, fix duplicate test, fix comment 
- Add ENSURE(result == Z3_L_TRUE) for each BNH optimization call and
  ENSURE(num_sat == 7) at the end so CI catches regressions.
- Remove test_bnh_optimize() from tst_api() to avoid duplicate
  execution under /a; keep standalone tst_bnh_opt() entry point.
- Fix Test 2 comment: it tests same-size backup, not backup-longer.

6d890fb026 Fix NLA optimization regression and relax restore_x 
- Relax restore_x() to handle backup/current size mismatches: when
  backup is shorter (new columns added), call
  move_non_basic_columns_to_bounds() to find a feasible solution.
- Fix 100x performance regression in nonlinear optimization: save LP
  optimum before check_nla and return it as bound regardless of NLA
  result, so opt_solver::check_bound() can validate via full re-solve
  with accumulated NLA lemmas.
- Refactor theory_lra::maximize() into three helpers: max_with_lp(),
  max_with_nl(), and max_result().
- Add mk_gt(theory_var, impq const&) overload for building blockers
  from saved LP optimum values.
- Add BNH multi-objective optimization test (7/7 sat in <1s vs 1/7
  in 30s before fix).
- Add restore_x test for backup size mismatch handling.

Fixes #8890

8a146a92ec fix: replace UNREACHABLE with VERIFY for non-COI constraint/monic violations in nra_solver 
The NRA solver's check() uses cone-of-influence (COI) to select a subset
of constraints for nlsat. When nlsat returns l_true, the model is validated
against all constraints, but non-COI constraints can legitimately be
violated since nlsat only solved over the COI subset.

- Non-COI violations gracefully return l_undef (fallback to other strategies)
- COI violations still trigger an assertion (indicating a real nlsat bug)

Fixes #8883
