Register a callback invoked immediately after data is pushed to the input ring buffer.

Called from USBUartComponent::loop() in the main loop context. Allows consumers (e.g. ZigbeeProxy) to process bytes in the same loop iteration they arrive, eliminating one full main-loop-wakeup cycle of latency.
