libtmux::CommandOperation::wait_until(deadline: std::chrono::steady_clock::time_point) -> expected< bool, CommandFailure >
```

True means the result can be taken; false means only this wait expired.

Neither outcome consumes the handle or changes the command's deadline. A consumed or moved-from handle reports FailureKind::validation.
