fix(server): Codex works again after its app-server is killed#26188

apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts: 1

715-862: External image Trivial · Functional Correctness · Quick win

Preserve active-turn synchronization while testing buffered events.

runtime.events reads directly from the queue, and Queue.fail delivers buffered items before the failure. The inactive cases currently consume turn.terminal before termination, so they do not test that behavior. Keep the turnStarted wait, interrupt the reader after it consumes the running event, enqueue the terminal event, and start a new reader after termination.
