From whitepaper §11.2: Implement φ-optimized fused multiply-add, multiply-subtract, and fused multiply-add-mul-sub in GF16 format
Background: Current IGLA-GF16 architecture uses standard GF16 format without φ-optimization for arithmetic operations. Need to implement:
- GF16 fused operations: add/sub/mul/sub (1:6:9 format)
- φ-optimized FMA: Use φ-based scaling factors
- Reference: whitepaper §11.2 (GF16 format 1:6:9 with φ ratio)
