## 구현/정리 내용

- `WsClient.getMetricsDiagnostics()` is internal while crosstest can compile through associated source sets.
- `BaseClient`, `WsClient`, `TcpClient`, and `WsServer` close/cleanup ownership was clarified to avoid recursive transport close and stale WSS server clients.
- Kotlin WSS tests use deterministic cleanup/readiness checks and TLS test setup is stabilized for local self-signed handshakes.
- Heartbeat tests close clients in `finally` and wait for heartbeat emission deterministically.
