Function: resolveSupportedDevices()

function resolveSupportedDevices(
   registry: DeviceRegistry, 
   protocols: ReadonlySet<string>, 
   transports: ReadonlySet<TransportType>): SupportedDevice[];

Filter a registry down to the devices a host runtime can actually drive, given the set of registered protocols and transport implementations.

Two dimensions, deliberately kept separate:

• Engine coverage is a property of (device, PROTOCOLS) — stable per package version. Drives the "is this device supported by this driver" verdict (allEnginesDrivable).
• Transport coverage is a property of (device, TRANSPORT_IMPLS) — varies by host runtime. Surfaced as drivableTransports / undrivableTransports; consumers compose their own UI from the arrays.

A device with usb + tcp + bluetooth-spp on a Node host without SPP is fully supported in every sense the user cares about — the missing SPP is a per-transport hint, not a device-level demotion.

The resolver also filters out devices with zero drivable transports or zero drivable engines — they cannot be opened or printed to from this runtime, so there is nothing useful to surface.
