Fixes intermittent test failures in CI (#6282) 
I'm seeing two tests fail intermittently in CI. This PR attempts to
address (or at least mitigate) the flakiness.

* summarize_context_three_requests_and_instructions - The test snapshots
server.received_requests() immediately after observing TaskComplete.
Because the OpenAI /v1/responses call is streamed, the HTTP request can
still be draining when that event fires, so wiremock occasionally
reports only two captured requests. Fix is to wait for async activity to
complete.
* archive_conversation_moves_rollout_into_archived_directory - times out
on a slow CI run. Mitigation is to increase timeout value from 10s to
20s.

codex-app-server

codex app-server is the harness Codex uses to power rich interfaces such as the Codex VS Code extension. The message schema is currently unstable, but those who wish to build experimental UIs on top of Codex may find it valuable.

Protocol

Similar to MCP, codex app-server supports bidirectional communication, streaming JSONL over stdio. The protocol is JSON-RPC 2.0, though the "jsonrpc":"2.0" header is omitted.

Message Schema

Currently, you can dump a TypeScript version of the schema using codex generate-ts. It is specific to the version of Codex you used to run generate-ts, so the two are guaranteed to be compatible.
