Summary

Implements IGLA-GF16 Modules 1 and 5 from #3.

Module 1: Trinity Constants (src/trinity_constants.zig)

• PHI, PHI_SQ, PHI_INV, PHI_INV_SQ, TRINITY
• ALPHA_PHI = PHI - 1.5 = 0.118034 (strong coupling constant)
• Fibonacci array {1..987} and architecture constants (d_model=144, d_ffn=233)
• Trinity weight init stds: gauge/higgs/lepton/cosmology sectors

Module 5: φ-LR Schedule

• Warmup over Fib(7)=21 steps, then φ-decay
• LR_INIT = ALPHA_PHI, LR_TAU = 228.9
