## 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 establishes a
non-mutating end-to-end plugin smoke workflow before any analytics
identity semantics change.
- Add `plugin-analytics-smoke` to the existing app-server test client.
- Exercise plugin disable, enable, and use through production app-server
RPC paths.
- Isolate config writes in a temporary file and use a loopback Responses
API server.
- Capture analytics without sending them to the production analytics
backend.
- Validate the current local `plugin_id`, names, capability metadata,
thread, turn, and model fields.
This is intentionally a baseline smoke workflow. It does not assert
`remote_plugin_id`; the final PR will update it when that field exists.
Review this PR as the net diff against #27093.
## Testing
- The test-client target compiles successfully.
- The combined reference branch exercised the manual smoke against the
live remote plugin service.
- CI is green across the required platform matrix.
