Detailed Description

IIO receive streaming thread for the ADALM-PLUTO.

Owns its own iio_context connection (cf-ad9361-lpc) so that it does not share state with PlutoCtrl or PlutoTX. The Pluto hardware is run at 2.5 MSPS (4× the SoDaRadio IF rate of 625 kSPS). Each IIO buffer refill yields ~30258 samples at 625 kSPS after 4:1 decimation via SoDa::ReSampler; an accumulator accumulates until 30000-sample CBufs can be published to BaseBandRX on rx_stream.

The IIO buffer is refilled continuously once started (same policy as USRPRX) so that the DMA pipeline never stalls. Upstream samples are discarded when streaming is disabled (TX half-duplex mode).
