- RX hw-gain (Pluto/AD936x): backend SetRxGain(ModeIdx, GainDb) — gain_control_mode (manual/fast_attack/slow_attack/hybrid) + hardwaregain. Controller FRxGainMode/ FRxGainDb, commands SetRxGainMode/SetRxGain/RxGainBy, rfRxGain event, snapshot, applied in StartRunning. Persisted per-device (rx_gain_mode/rx_gain_db). HPSDR unaffected (backend no-op). - UI: separate "RF AGC" panel below the (unchanged) WDSP AGC block, shown only for Pluto — FAST/SLOW/HYB/MAN mode buttons + manual GAIN slider. LayoutLeftPanel reflows lower panels via RelayoutBelowBands; no layout shift on HPSDR. - Cold-init fix: direct sampling_frequency write doesn't load the AD9361 FIR decimation filter, so a cold-booted Pluto showed a wide centre spike that didn't track tuning (worked only after SDR Console pre-initialised it). Add optional libad9361 binding (dynamic) and call ad9361_set_bb_rate() in ApplySampleRate, which configures BBPLL + loads the FIR; falls back to direct write if absent.
