Summary

This completes the analytical constraint Jacobian unit tests. Started from #38 (thanks @PhilipFackler) and
used Claude to help identify the differences in the network generation scripts and the bug in the reference solution assembly.

• Equality (jac_eq_acopf) and inequality (jac_ineq_acopf) tests: reference base Jacobians in cecj.csv / cicj.csv, tiled to the number of copies.
• Fix: inequality reference Jacobian row scaling for multiple copies (generator and line rows).
• New variant: inequality test without line limits (zero line ratings, -no_line_limits, cicj_nolinelimits.csv).

These are CPU-only tests. GPU tests with these analytical solutions are future work, as they require some cleanup of the interface. HIOPSPARSEGPU is covered by covered by test_eqjac_gpu, test_hess_gpu and test_ineqjac_gpu using some tricks to call the GPU methods directly.
