--spi used to take whichever SPI profile config.toml listed first, a coin toss that transmits once two radios are configured. It now counts the radios actually attached: exactly one is used whether or not a profile names it, which keeps the common single-radio case to a bare --spi. Two attached, or two SPI profiles with nothing attached to count, is a selection error (exit 3) that lists them and asks for -p, the same way several serial devices with no default already are.
