## What changed
Add a cross-platform pytest suite that extracts the CLI and app-server
archives and verifies:
- common CLI discovery commands;
- code-mode execution through both packaged entrypoints, including use of each
package's bundled `rg`; and
- the presence and usability of packaged debug symbols on Linux, macOS, and
Windows.
The suite accepts gzip or zstd package archives and isolates its Codex
configuration and state from the invoking environment.
