blake3@1.8.5

blake3 1.8.5 is the official Rust BLAKE3 implementation with SSE2, SSE4.1, AVX2, AVX-512, NEON, and WASM SIMD backends. No issues found. Unsafe is pervasive in the SIMD paths but systematically documented and bounded by runtime feature detection; all backends are cross-checked against a reference implementation via randomized tests and a Miri smoketest in CI. Hash equality is constant-time. The build script writes outside OUT_DIR on Windows MinGW (clang-cl cleanup), reflected in build-exec-no-write-out.
