chore: release v0.20.9

Multi-amp: Settings->Amplifier becomes a list (amps.json, legacy single-amp keys auto-migrate to entry #1); one client per enabled amp with per-id bindings (GetAmplifiers/SaveAmplifiers/GetAmpStatuses/AmpOperate/AmpPower/AmpPowerLevel/AmpFanMode); legacy a.pgxl/a.spe/a.acom point at the first enabled amp of each family. Amp cards in FlexPanel and Station Control gain a dropdown to pick the amp; the status bar shows one clickable chip per amp. Use case: two SPEs run in parallel.

Flex v4 DSP (8000/Aurora): NRL/ANFL (lms_nr/lms_anf), NRS (speex_nr), NRF (nrf) with level sliders, RNN (rnnoise) and ANFT on/off — keys per the FlexLib slice docs; the section only shows when the radio reports these keys (dsp_v4 flag), so 6000-series panels are unchanged.

+// Package gs232 drives rotator controllers that speak the Yaesu GS-232A
+// protocol, over a raw TCP socket or a serial COM port. The target device is
+// the microHAM ARCO: both its LAN "CONTROL PROTOCOL" setting (a TCP port) and
+// its USB port ("USB CONTROL PROTOCOL", a virtual COM where the baud rate is
+// irrelevant) can be set to speak Yaesu GS-232A — so OpsLog controls it
+// directly, no PstRotator in between. ARCO accepts up to four parallel LAN
+// connections, and commands are single CR-terminated lines, so short
+// per-call connections (same idiom as the other rotator backends) work fine.
+//
+// GS-232A subset used:
+//
+//	Maaa<CR>  move to azimuth aaa (000-450)
+//	S<CR>     stop rotation
+//	C<CR>     query azimuth — replies "+0aaa" (GS-232A) or "AZ=aaa" (GS-232B
+//	          flavour); both are parsed.
