allaun f75384082e feat(lean): add applyViscosity_energy_le and AVMR ODE scaffolding
Item 1 (BurgersPDE): Added Q16_16.mul_sq_le_sq lemma and applyViscosity_energy_le general theorem — the universal energy dissipation result that subsumes all 5 point-evaluation proofs.

Item 7 (AVMRTheorems): Added Float-free vectorFieldℝ, Lipschitz proof, ε=0 base_dynamics, and ode_existence (with TODO) for the missingLinkODE continuum limit. Also fixed broken proofs: tipCoordinateMassResonance corrected to mass ≤ (k+1)² only; massResonanceMax → massMidpoint (correct: mass = k·(k+1)); replaced Nat.sqrt_eq_iff_sq_le (removed in Mathlib 4.30) with inline le_antisymm + Nat.le_sqrt proofs; fixed import paths; fixed omega/nlinarith failures in AVMRCore.

Build: 3571 jobs, 0 errors (Semantics workspace), 8315 jobs, 1 sorry (ode_existence TODO)

These 4 special positions on each shell correspond to
the 4 nucleotide bases, mapping structural features
to biochemical properties:
- a (n = k²): Purine, 2 H-bonds (A)
- g (n = k² + k): Purine, 3 H-bonds (G)
- c (n = k² + k + 1): Pyrimidine, 3 H-bonds (C)
