* @brief TCP/UDP implementation of DebugServiceI.
* @brief TCP/UDP implementation of DebugServiceI (via DebugServiceBase).
*
* Provides signal tracing (UDP), forced-value injection, break conditions,
* and a text command channel (TCP) with a log-forwarding sidecar (TcpLogger).
* Alternative transports (TTY, WebSocket, …) can be added by implementing
* DebugServiceI without touching this class or any broker wrapper code.
* All signal management and command dispatch logic lives in DebugServiceBase.

* - Hold clientMutex whenever assigning (including to NULL) activeClient.
