## Why Windows MSVC builds relied on installed C++ toolchains, and V8 snapshot generation required native Windows execution. Cross-compiling V8 also needs a Windows snapshot generator to preserve Windows unwind metadata. ## What changed - Use the registered hermetic LLVM toolchain and declared Microsoft SDK for Windows MSVC builds, with static CRT linkage and the toolchain's declared `lld-link` for Rust. - Run Windows V8 snapshot generators natively or through `rules_wine` on Linux, preserving target CPU, OS, and sandbox settings. Keep separate archive and binding pairs for the workspace's ISO stdio ABI and the distributed MSVC stdio ABI. - Update build dependencies and bindgen, scope V8's Chromium libc++ settings to its own targets, and adapt native voice dependencies for clang-cl and Windows ARM64. - Build SQLite directly with Bazel and give `openssl-sys` an explicit build using Bazel's OpenSSL. - Remove build-worker source-directory dependencies from Bazel resource lookup, schema output discovery, and snapshot paths; embed assets in debug builds as well.
