* Software RSSI: 8 packed I/Q samples from baseband_thread.

* baseband_thread copies 8 samples spread across buffer (no computation).
* Each sample is packed: Q in high 16 bits, I in low 16 bits.
* rssi_thread uses __SMUAD on each to compute I²+Q², finds peak.
*
* 8 samples avoids zero-crossing artifacts from single-sample approach.
