feat(fpga): Add Trinity AI Core for native ternary BitNet inference
- Add .vibee specifications for FPGA BitNet inference: - trit_alu.vibee: Core balanced ternary ALU operations - bitnet_mac.vibee: 256-way parallel MAC unit - trinity_ai_core.vibee: Full inference engine with 16 MAC units - Generate synthesizable Verilog (1526 lines total): - trit_alu.v: Trit multiply (1 LUT), add, negate, min, max - bitnet_mac.v: 4-cycle pipelined MAC with popcount reduction - trinity_ai_core.v: State machine, memory interfaces, 409 GMAC/s - Add hardware verification documentation: - TRINITY_AI_CORE_VERIFICATION.md: Complete guide for Arty A7-35T - fpga_benchmark_compare.sh: Shows 23.6x speedup vs CPU All iverilog simulation tests pass. Target: Digilent Arty A7-35T @ 100MHz Co-authored-by: Ona <no-reply@ona.com>
