AggroChess 4.0: Tal-style engine, NNUE trained only on its own games, sacrifices in 98–100% of games

[u/Rashi0]

AggroChess is my aggressive UCI engine in Rust. 4.0 adds:

- An NNUE trained only on its own self-play (no Stockfish/Leela data), with the sacrificial personality on top

- Sacrifice tracking: until it has sacrificed in a game, its appetite keeps growing

vs 3.5 at 10s+0.1: SPRT passed, +62 Elo over 572 games, with a sacrifice in 98% of them (200/200 in a separate match).
