Captures the architecture, operator workflow, and verification for
running the Connect ZBT-2 as an OpenThread Border Router on jupiter
(via nixos-unstable's services.openthread-border-router module),
with HA's otbr + thread integrations driving the Thread network
and the existing matter-server consuming credentials for
Matter-over-Thread device commissioning.
Supersedes the ZHA-direction commit on this branch (e8d09f4),
which will be reverted at the start of implementation.
