## What changed
- Add explicit x64 and ARM64 targets for native builds, runtime preparation, and linking using the existing voice recipes. Each target requires native Windows execution of the matching architecture.
- Declare compiler, SDK, Python, and CMake inputs; require an explicitly supplied Cygwin/pkgconf tool tree and a fixed `SystemRoot`. Validate installed tool selections against the manifest and declared files.
- Pair Windows DLLs with SDK import libraries, preserve plugin and receipt runfiles, and omit Unix runtime-search flags. Use Python for portable payload copying.
- Correct the MSVC ARM64 tool directory casing to `HostArm64` and document provisioning and build commands.
The generic Rust-consumer aliases remain separate; native Windows Bazel execution and consumer validation are still needed to establish complete Windows voice support.
## Testing
Add eight unit tests covering tool selection, path anchoring, invalid inputs, and DLL/import-library copying, plus x64 and ARM64 link smoke targets that reference `gst_version`.

## What changed
- Export `native_sdk` from the same inspected build as `native_runtime`.
- Configure GLib and GStreamer Rust build scripts to use the declared `pkg-config` executable and SDK, preserving upstream version checks while directing linking to prepared libraries.
- Add `native_link` to expose canonical libraries, development aliases, transitive dependencies, plugins, and the runtime manifest through `CcInfo` and runfiles. Replace GStreamer SDK absolute rpaths with relative Bazel runpaths.
## Testing
Extend the macOS archive preparation test to cover absent and empty SDK output directories, verify SDK file hashes, and check that SDK and runtime manifests share the same source commit and target.
