## What changed
- Add a `dsymutil` wrapper that delegates to the C toolchain's `LLVM_DSYMUTIL`, and include it in macOS Rust binary compile inputs and `PATH` so `rustc` can find it by name.
- Build macOS release staging archives with `--config=ci-macos`, `--remote_download_toplevel`, and `--build_metadata=VISIBILITY=PRIVATE`.
