```
test.TestServerBuilder.lifecycle_timeout(mut, timeout: Duration) -> Self
```

Configure the bounded startup and graceful-shutdown observation time.

On targets without a safe non-reaping child-exit observer, the graceful
shutdown phase is capped at five seconds before forced cleanup.

## Example

```rust
use libtmux::test::TestServer;

let _builder = TestServer::builder()
    .lifecycle_timeout(std::time::Duration::from_secs(1));
```
