Orca terminals run under the signed helper, whose executable was stock Node,
sharing its LC_UUID with every install of that Node build. macOS Local Network
privacy maps a responsible process to an app by that UUID, so terminals could be
attributed to another program and blocked from the LAN while Orca showed allowed.
Rewrite the helper executable's UUID during assembly (same scheme as #41676),
and fail packaging and the release check if it drifts.
Fixes#21988
