## Why The Bazel V8 source build supported Windows GNU but lacked an MSVC-targeting toolchain to produce `*-pc-windows-msvc` archives. ## What changed - Add opt-in archive targets for native Windows x64 and ARM64 hosts, selected by `//third_party/v8:rusty_v8_native_windows_archive_for_target`. - Fetch pinned LLVM and scope its `clang-cl` toolchain to V8 artifacts, using the installed Microsoft SDK. Bundle Chromium libc++ and compiler-rt builtins into the resulting `.lib`. - Adapt V8 dependencies, assembly, snapshot generation, and platform feature settings for MSVC, and derive test metadata from the selected engine features. - Document the native build workflow. Existing MSVC consumers continue using prebuilt artifacts; generated Rust bindings and publishing integration remain separate. GitOrigin-RevId: abd5049245aece90a116fc3bfeac2b158a76f6af
