## This PR
The original [combined remote plugin analytics PR
#26281](https://github.com/openai/codex/pull/26281) mixed reusable
analytics test infrastructure, two manual smoke workflows, a metadata
refactor, and the final identity behavior. This PR adds the
account-mutating validation workflow separately so its cleanup and
recovery guarantees can be reviewed without the final analytics behavior
change.
- Add a manually invoked remote plugin install/uninstall smoke workflow.
- Require explicit account-mutation confirmation and an initially
uninstalled plugin.
- Validate the current `codex_plugin_installed` contract, where
`plugin_id` is the backend ID.
- Restore and verify the original uninstalled state, with a dedicated
recovery command.
This baseline intentionally does not require `codex_plugin_uninstalled`,
because production does not emit that event yet. The final PR will
update this smoke to require local `plugin_id`, `remote_plugin_id`, and
uninstall emission. Review this PR as the net diff against #27099.
## Testing
- `just test -p codex-app-server-test-client` (3 focused
capture/validation tests passed)
- The live workflow was previously exercised on the green combined
reference branch, and the original uninstalled account state was
restored.
- CI is green across the required platform matrix.
