Brandon Schneider b54f597690 feat: ARM64 copy-if optimizer — branches to CSEL 
Transforms branch patterns to ARM64 conditional selects:
  Before: CMP + BEQ + compute + B + MOV = 5-47 cycles
  After: CMP + compute + CSEL = 4-6 cycles

ARM64 CSEL instruction:
  CSEL Xd, Xn, Xm, cond
  - Single cycle on most ARM64 processors
  - No branch prediction penalty
  - No pipeline flush on mispredict

Pattern detection:
  - CMP + BEQ/BNE/B.LT/etc
  - True block: 1-3 compute instructions + B
  - False block: single MOV
  - Merge point

Same pattern as:
  - SPIR-V OpSelect (GPU shaders)
  - VCN delta+RLE (3.3x)
  - QR spatial hash (2.18x)
  - Lean CopyIfTactic (2.7x)

Works on ARM64 assembly from GCC/LLVM/Rust.
No compiler fork needed — post-processing pass.

Targets: Neon-64GB (18 vCPU ARM64 EPYC)
