test: add end-to-end skewed-torus and synthetic holonomy Re(τ)<0 tests

Finding-H from doc/reviewer/external-audit-2026-05-30.md
(java-port-audit missing-test item 7).

Guards against a regression where compute_period_matrix reverts to
reduce_to_fundamental_domain (no mirror fold) instead of normalizeModulus
(Finding 6 fix, Java-faithful): such a revert would silently produce
Re(τ) < 0 for lattices where the natural generators give a negative
real part.

Two new tests in test_phase7.cpp:

1. SkewedTorus_ReTauNegativeBeforeNorm_FoldedToPositive
   - New mesh: code/data/off/torus_skewed_4x4.off
     Flat 4×4 torus on parallelogram lattice ω₁=(4,0) ω₂=(-1,4);
     16 vertices, 32 triangles, χ=0 (genus 1).
   - Full pipeline: newton_euclidean → cut_graph → euclidean_layout
     → compute_period_matrix(reduce=false) + compute_period_matrix(reduce=true)
   - Asserts: raw Re(τ) < 0, normalized Re(τ) ∈ [0,½], Im(τ) > 0, |τ| ≥ 1

2. SyntheticHolonomy_NegativeReTau_NormalizedToPositive
   - Bypasses mesh; supplies explicit ω₁=(4,0) ω₂=(-1,4) directly
   - Asserts raw τ = -0.25+i (to 1e-10), normalized τ = 0.25+i (to 1e-9)
   - Pin-points the mirror fold: Re(-0.25) → Re(+0.25)

277/277 CGAL tests pass, 0 failed.

docs: Mathematiker-Onboarding — Theorie, Validierung, Beispiel-Meshes, 170 Tests

C++ Tests / test-fast (push) Successful in 2m20s

Details

C++ Tests / test-cgal (push) Has been skipped

Details

Ziel: einem interessierten Mathematiker ermöglichen, die bisherige Arbeit
      unabhängig zu validieren und eigene Forschung beizutragen.

Neu:
  doc/math/discrete-conformal-theory.md
      Kompakte mathematische Einführung (DCE, Variationsprinzip, drei
      Geometriemodi, Holonomie, Periodenmatrix) für Riemann-Flächen-Kenner.

  doc/math/validation.md
      Analytisch bekannte Sollwerte + wie man sie mit dem Code prüft:
      Gauss–Bonnet (χ), τ ∈ Fundamentaldomäne (3 Invarianten), Symmetrie-
      Argumente für τ=i (4-fach) und τ=e^{iπ/3} (6-fach), Newton-Konvergenz,
      Gradienten-Check (FD), Holonomie-Kommutator. Reviewer-Checkliste.

  CONTRIBUTING.md (Root)
      Gitea/GitHub-Standard: CONTRIBUTING.md im Root-Verzeichnis als
      Kurzreferenz mit Links zu doc/contributing.md und den Math-Docs.

  code/data/off/torus_4x4.off   — 16 Vertices, 32 Flächen, Genus 1
  code/data/off/torus_8x8.off   — 64 Vertices, 128 Flächen, Genus 1
  code/data/off/torus_hex_6x6.off — 36 Vertices, 72 Flächen, 6-fach Sym.

Aktualisiert:
  README.md              — 158 → 170 Tests, zwei neue Math-Links in Tabelle
  doc/api/tests.md       — 28 Suiten, 170 Tests, 1 Skip (korrigiert)
  doc/contributing.md    — Testzähler 158+2 → 170+1
