Add a lightweight N-1 security-constrained AC OPF independent of the GOC3
machinery, in both monolithic and Schur-decomposable forms:
- scopf_model (src/scopf_simple.jl): replicates the base AC OPF across a
scenario dimension (column 1 = base, 2..K+1 = contingencies), supporting
generator and branch outages with bounded corrective generator recourse.
Includes the MATPOWER rateA == 0 ("unlimited") fix. polar and rect forms.
- scopf_twostage_model (src/scopf_twostage.jl): the same problem on a
TwoStageExaCore (base = first stage, each contingency = an EachScenario
block), solved with MadNLP's SchurComplementKKTSystem; returns the Schur
partition tags as a 4th value.
- examples/scopf.jl: CLI-driven driver (case/mode/form/gpu/inertia/...) over
the matching <case>.Ctgs line-contingency list, plus case9/case118 data.
- test/scopf_tests.jl: case9 N-1 agreement test (CPU single vs CPU/GPU
two-stage) on objective and base/scenario dispatch, wired into runtests.jl.
- Pin MadNLP + MadNLPGPU to the schur-design-constraints branch via [sources]
so Pkg.test (local and CI) gets the SchurComplementKKTSystem support; the
registry release rejects it. README/docs touchups.
