tmuxtest.ControlMode.CloseContext(ctx: context.Context) -> error
```

CloseContext starts an idempotent shutdown and waits within ctx. Concurrent calls join the same shutdown. If ctx ends after shutdown starts, shutdown continues and a later call may wait for completion; an already-ended ctx does not start shutdown.
