VeillaxandClaude Sonnet 5.5 2259580adf Add the shared packages for the sharks stack
model, tunnel, wg, authtoken, netguard, docker and dotenv, split out of the
original single repository so Hammerhead, Blacktip and Bamboo can live in
their own repos and import them. README extended; LICENSE unchanged.
