feat(lean): add PhiNUVMAP — golden-ratio fractal 16D coordinate system

PhiNUVMAP lifts NUVMAP into a 16D golden-ratio-scaled fractal space:

- phiQ16_16 ≈ 4181/2584 (Fibonacci ratio, error < 10⁻⁹)
- phiInvQ16_16 = φ⁻¹ for exact golden contraction
- 16D vector ops: add, sub, scale, zero
- PhiNUVMAP structure: center + coords + scaleLevel + spectralMode
- Golden contraction law: s' = c + φ⁻¹·(s-c)
- Fractal zoom: zoom in (×φ) / zoom out (×φ⁻¹) by level
- Tree-to-16D projection: TreeDIAT → 16D φ-NUVMAP state
- 16D chaos game with φ-contraction and deterministic perturbation
- 13 #eval! witnesses: φ·φ⁻¹≈1, φ²=φ+1, contraction, zoom, tree projection,
  chaos game convergence

Build: lake build Semantics.PistSimulation = 3309 jobs green.

-- §8 PhiNUVMAP — Golden-Ratio Fractal 16D Coordinate System
-- ════════════════════════════════════════════════════════════
--
-- PhiNUVMAP lifts NUVMAP into a 16D golden-ratio-scaled fractal space.
--
-- Core insight: φ = (1+√5)/2 is the unique number where φ^2 = φ + 1.
-- This gives the Fibonacci recurrence, which yields self-similar tilings
-- at all scales — the definition of a fractal.
--
-- In PhiNUVMAP:
-- • Coordinates scale by φ (zoom in) or φ^(-1) (zoom out / contract)
-- • The space is naturally non-uniform: denser near the center
-- • The golden contraction law s' = c + φ^(-1)·(s-c) is exact
-- • TreeDIAT states project into this 16D space and contract toward
-- their anchor at the golden rate
