feat: implement EXACT Stockfish NNUE FullThreats encoding
...
- FullThreats formula: from_piece_idx * 157 + to_piece_idx
- Max index: 59,889 (within 60,720 limit)
- 24 HalfKAv2_hm + 79 FullThreats = 103 features
- All verification tests pass
- Matches Stockfish NNUE encoding structure

feat: implement HalfKAv2_hm feature extraction (352 features)
...
- Use oriented squares for piece encoding
- 24 pieces + 1 king bucket = 25 active features on starting position
- King bucket features prefer white king perspective
- All tests passing (11 tests)
