Detailed Description

Outbound authenticated exchange state machine (non-pairing flows).

Implements IOHomeControlComponent::send_and_receive_() and its stepwise helpers: transmit_request_(), wait_for_first_response_(), handle_authentication_(), wait_for_final_response_(). These functions encapsulate the retry loop, challenge-response authentication, and final response handling for commands sent to paired devices.

The exchange logic is separated from hub_core.cpp to keep the main loop and device-management concerns distinct from the protocol state machine. Pairing flows (discovery/key exchange) live in hub_pairing.cpp.
