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.

Existing single-amp setups migrate automatically.",

+// Package acom drives the ACOM solid-state amplifiers (500S / 600S / 700S /
+// 1200S / 2020S) over their (unpublished) RS-232 protocol, reverse-engineered by
+// the ACOM-Controller project (bjornekelund, C#). The amp is reached either
+// directly over a serial COM port (9600 8N1) or over TCP via an RS232-to-Ethernet
+// bridge — both are just an io.ReadWriteCloser to this code, same as the SPE
+// backend.
+//
+// Wire format (host → amp): fixed raw byte strings, validated by the same rule as
+// telemetry (sum of ALL frame bytes ≡ 0 mod 256):
+//
+//	enable telemetry:  55 92 04 15
+//	disable telemetry: 55 91 04 16
+//	OPERATE:           55 81 08 02 00 06 00 1A
+//	STANDBY:           55 81 08 02 00 05 00 1B
+//	OFF (power down):  55 81 08 02 00 0A 00 16
+//
+// Power ON is NOT a data command: it is a hardware pulse on the serial DTR/RTS
+// lines (the amp's remote power-on pins) — serial transport only, and only if the
+// cable wires those pins (a telemetry-only cable uses just RX/TX/GND).
+//
+// IMPORTANT: DTR and RTS must be held LOW at all times otherwise — asserting them
+// permanently blocks the amplifier's front-panel power button.
+//
+// Telemetry (amp → host): once enabled, the amp streams 72-byte frames starting
