## 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`.

## What changed
- Add `runtime_package` targets for combined, primary, app-server, and Windows helper bundles, plus per-binary release archives.
- Apply release settings automatically and retain unstripped binaries with macOS dSYM or Windows PDB symbols. Require platform-specific symbols and validate that dSYM bundles contain nonempty DWARF data.
- Support a `debug` build mode for faster package smoke builds and configure platform-specific release settings, including native Windows MSVC toolchains.
- Add a composite action that refreshes Cargo workspace metadata, builds the selected archive, and extracts writable files for existing signing and packaging steps.
