## Why
Cargo and Bazel embed different PDB filenames in the Windows code-mode host executable. The package smoke test must support both names while verifying that the debug symbols match the packaged executable.
## What changed
- Keep the archived PDB and copy it to `codex_code_mode_host.pdb`, allowing `dumpbin /PDBPATH` to resolve either name. Accept either path in the assertion.
- Set `sandbox_workspace_write.writable_roots = []` explicitly in the smoke-test configuration.

## 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.
