allaun 8bed931037 feat(lean): BlockCoprimeDensity — C(n) block-coprime density Euler product
Formalizes the Euler product for the natural density of (r, M) pairs
satisfying gcd(r, M+j) = 1 for all j = 0..n:

  C(n) = ζ(2) · ∏_p (1 − min(n+1, p) / p²)

Key theorems:
  - localFactor_saturated / localFactor_active (saturation partition)
  - C_finite_zero_eq_one (C_G(0) = 1 for any G, ζ(2) identity)
  - D_finite_zero_eq, D_finite_one_eq (Feller-Tornier product)

All 5 #eval witnesses verified. 0 sorries.
