## What changed
Add a `build-system` input to `build-codex-packages`, defaulting to `cargo`, and extract binary builds into dedicated Cargo and Bazel actions. The Bazel path stages binaries and symbols for the shared CLI and app-server packaging and smoke-test steps, with support for `release` and `debug` build modes.
Resolve the package source root before invoking nested actions, and use Bash to export the Bazel repository cache path.
