## What changed
Add `//third_party/voice:native_prefix` to run the existing native build recipe with Bazel-declared archives and toolchain inputs on matching macOS and Linux GNU 2.28 targets for x64 and ARM64. The manual target exports `prefix.tar` and a `built.json` receipt through the `receipt` output group.
Keep macOS actions local to access Apple tools, use Apple's linker for libffi partial links, and preserve compiler runtime flags through libtool on Linux. Surface upstream build failure logs in the Bazel action output.
Document the build's host utility requirements and the distinction between the raw prefix and a relocatable SDK or runtime package.

## What changed
- Pin the GStreamer, codec, native library, and build-tool archives needed by
the native voice runtime, including their SHA-256 digests.
- Add lazy Bazel repositories and a manual `//third_party/voice:sources` target
for fetching and unpacking the pinned archives.
- Add an offline Python adapter that verifies archive identity and extraction
bounds, refuses existing output directories, cleans up failed preparations,
and records a completion receipt.
- Document that this stage prepares source inputs only; it does not compile or
link the libraries or enable voice.
## Testing
- Add unit coverage for digest failures, unsafe links, expansion limits,
cleanup after extraction failures, existing-output preservation, and systems
where archive links cannot be created.
