Module client 

Provides the WebSocket client integration for the OKX WebSocket API.

The OKXWebSocketClient ties together several recurring patterns:

• Heartbeats use text ping/pong, responding to both text and control-frame pings.
• Authentication re-runs on reconnect before resubscribing and skips private channels when credentials are unavailable.
• Subscriptions cache instrument type/family/ID groupings so reconnects rebuild the same set of channels while respecting the authentication guard described above.
