Update NNUE architecture to SFNNv18 and net nn-c9e480e92425.nnue Introduce the SFNNv18 NNUE architecture: - Replace HalfKAv2_hm with K32Q2 feature set, conditioning on own king position (32 buckets) and opponent queen presence (2 states). - Expand layer stacks from 8 to 32, indexed by piece count and queen bucket (pc_bucket * 4 + queen_bucket). - Quantize feature transformer weights to int8 and simplify parameter serialization to uncompressed little-endian format, removing LEB128 routines. - Update accumulator management and Finny table caches to track opponent queen presence, requiring accumulator refresh on king moves and opponent queen captures or promotions. - Update default net to nn-c9e480e92425.nnue.
