Detailed Description

Z_ii sweep — the SIA-SIA coalescence bias factor.

Z_ii multiplies the full K_ii_coal rate (SIA absorption by SIA loops)
but does NOT affect vacancy absorption. This makes it the primary knob
for shifting the growth/shrink balance.

With corrected loop geometry (A_loop * n^{1/2}):
  growth_ratio = Z_ii * Z_i_loop * Di * c_i1 / (Dv * c_v1)

Baseline ratio ≈ 0.742 at Z_ii=1.2.  Need ratio > 1.0 for net growth.
Estimated crossover: Z_ii ≈ 1.6-1.7.
