A LoRa chip on the host's own SPI bus (the uConsole AIO) is now a
transport like serial, BLE, and TCP: --spi, an SPI profile, or the
picker's row for /dev/spidev1.0. MeshTerm starts a software node as a
child process under whichever Python has openhop-core, talks to it over
a loopback port, and ends it on disconnect; the node also exits with its
parent, so the pins are free whenever MeshTerm is not running.
The node keeps identity, prefs, channels, and contacts under
~/.meshterm/radio/<spidev>/, and on first use copies the bridge's
identity, contacts, and radio settings so it stays the same node.
Board wiring lives in a profile's spi table; radio settings are the
node's own, edited on Device config. Closes#21.
