perf: drop the pext slider path and the -pext binaries Since AVX2 builds compute slider attacks by hyperbola quintessence, the pext lookup only ever applied to targets that have BMI2 but not AVX2, which is not a combination worth carrying a second slider implementation for. Stockfish reached the same point and removed its pext path outright. That also collapses the release matrix. avx2-pext differed from avx2 only by -mbmi2, and avx512-pext existed because every AVX-512 part has BMI2, so both names now describe nothing. The Windows build script ships four binaries instead of five: x86-64, sse41, avx2, avx512. No functional change on any AVX2 host: the emitted code for a native build is byte identical before and after. Co-authored-by: Claude Agent <claude@home.arpa>
