Brandon Schneider 1872b69ba7 feat(physics): DESI invariant and 16D horn-fiber model projection
Add two Lean modules projecting the Menger/Koch/Gabriel-Horn fiber model
onto DESI DR2 cosmological observables:

- DESIInvariant.lean: Hardcoded DESI DR1/DR2 constants as Q16_16 Int
  literals. Zero Float arithmetic. 7 observational parameters + sigma
  bounds. 5 native_decide theorems. 7 eval! receipts.

- DESIModelProjection.lean: Maps 16D model predictions onto DESI
  observables. 4-component residual computation with verdict
  classification. 17 native_decide theorems proving:
    * All 4 observables within 1s of DESI DR2
    * Directional agreement on w0 > -1, wa < 0
    * Menger/Koch geometric facts (d_H < 3, D_K < d_H, divergence > 1)
    * Horn volume bounded, surface grows, torsion drives boundary
