The headless daemon (ewsdrd) only ever built HPSDR devices, so Pluto
could not be used: backend is chosen by Dev.Kind and Pluto opens by URI,
neither of which the daemon propagated. Also local audio played on the
host and web Discover never probed network Plutos.
Shared, backend-agnostic helpers in TRadioController (used by GUI + daemon):
- ResolveDevice(IP): discovered->saved lookup restoring Kind/URI/Serial/
BoardType/MAC. MainForm.ResolveDevice now delegates here.
- AddSavedDevice(name, addr): web dev_add saves Pluto when addr has a URI
scheme (ip:/usb:/local:), else HPSDR. Both web hosts use it.
- SeedPlutoProbeFromSaved: seed network-probe URIs from saved Plutos
(no mDNS -> a network Pluto is only found by direct URI probe).
- LocalAudioEnabled flag (GUI=True): when False the local sound card is
neither opened nor written; RX audio goes only to web (OnAudioConsume).
DeviceStore.AutoStartDevice(out Dev): full autostart record (Kind/URI/
Serial) so a saved Pluto (URI-addressed, empty IPAddress on USB) can
autostart.
Daemon (ewsdrd.lpr): LocalAudioEnabled:=False; SyncConnect via
ResolveDevice; autostart via AutoStartDevice; SyncDiscover seeds probe
URIs then Discover; SyncDevAdd via AddSavedDevice.

Add ADALM-Pluto / AD9361 support as a second hardware backend alongside
openHPSDR, sharing the WDSP DSP pipeline and the existing controller API
(UI stays decoupled from logic).
- RadioBackend.pas: abstract TRadioBackend + TBackendCaps + TRadioDevice
(Kind/URI/Serial). THPSDRNetwork now derives from it (state via virtual
getters); TRadioController.FNetwork is the base type.
- IIOBindings.pas: dynamic libiio loader (runs without libiio present).
- PlutoBackend.pas: scan/probe-by-URI, connect, LO/rate/bandwidth/gain
control, RX streaming thread (int16->24bit BE -> OnDDCIQ), Q conjugated
to match WDSP IQ convention. Verified on LibreSDR (AD9361) over network.
- Unified discovery: TDiscoverThread scans both backends; network Plutos
found via direct ProbeURI (no mDNS needed). ConnectDevice dispatches by
Dev.Kind (EnsureBackend swaps backend, preserving callbacks).
- DeviceStore/DeviceForm: persist Kind/URI/Serial; save Pluto via
AddSavedPluto so saved/autostart devices reconnect across restarts.
- VHF/UHF band plan (BoardUtils, kind-aware): 6m..ADS-B for Pluto; fixes
HF clamps (band detect, mouse-wheel 60 MHz cap, freq-display max).
- SampleRateOverlay: configurable presets (Pluto 576k..5760k, >520 ksps),
auto-width to fit.

Introduce DeviceStore.pas (TDeviceStore) as the single source of truth for
saved devices (hpsdr_devices.ini CRUD + autostart) and the current discovery
list. The controller owns one instance (created/freed in its ctor/dtor);
desktop and (later) web frontends edit/render through it so the lists never
diverge.
Refactor TDeviceDialog to use a TDeviceStore reference instead of its own
arrays + ini code. MainForm wires FDeviceDialog.Store to the controller's
store, routes discovery results (DoAddDevice) and the preload-rate lookup
through it (TDiscoveredDevice now carries the MAC), and drops the now-unused
FDevices/TDeviceItem. Behavior-preserving for the desktop dialog.
