## What changed
Add `build-codex-packages` to build unsigned CLI and app-server packages for a supplied Rust target and package version. Support release optimizations or faster, unoptimized builds using the release profile.
Prepare platform-specific tools and bundled binaries, archive debug symbols, and produce both `.tar.gz` and `.tar.zst` packages.
## Testing
Run the existing package smoke tests against both compression formats and the symbols archive. Reject host `rg`, and host `bwrap` on Linux, on `PATH` so the tests exercise packaged tools.
