Implement full tunnel host capability for the Go SDK, enabling Go programs to act as tunnel hosts: register endpoints, connect to the relay over WebSocket, accept client connections via SSH, and forward traffic to local TCP ports. Key features: - V2 relay protocol with direct port forwarding (no nested SSH) - V1 protocol support with automatic fallback - Reconnection with exponential backoff - Automatic access token refresh - Connection status callbacks - Dynamic port management (AddPort, RemovePort, RefreshPorts) - Concurrent client support - Comprehensive unit and E2E test coverage Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
