Muon Mass NNLO: Two-Loop G₂-Orbit Structure and the sin(π/16) Structural Candidate

Verifies every explicit numerical claim in P133 from first principles:
  §1  Setup          — NNLO Dyson structure, Delta target 7.0×10⁻⁶

  §3  Candidates     — Cand A: 1/N_Fano = 0.200 → 7.20×10⁻⁶ (+2.9%)
                       Cand B: sin(π/16) = 0.19509 → 7.03×10⁻⁶ (+0.4%)
                       Table: 1/(2φ²) → 6.88×10⁻⁶ (−1.7%)
                       Table: tan(π/16) → 7.17×10⁻⁶ (+2.4%)
