generate-certs.sh mints the bus CA and a NATS server certificate whose SANs
cover the public IP (135.125.201.30), the WireGuard IP (10.42.0.1), the om
hostname, and localhost/127.0.0.1 for on-host smoke tests (all overridable via
env). Only the public ca.crt is committed; ca.key, server.key and server.crt
are gitignored and distributed out of band. README documents generation, use
and rotation.
