fix(ci): match real runner labels + survivable Mac runner daemon

runs-on: ubuntu-24.04 (the label the existing Linux runner actually
advertises — ubuntu-latest queued forever). Mac runner: strip the
docker:// default labels generate-config seeds (they override the
host-mode registration labels and make the daemon demand a Docker
engine), and ship the service as a root LaunchDaemon — macOS Local
Network privacy silently blocks LAN dials from unbundled CLI binaries
in gui/user launchd domains ("no route to host"), system daemons are
exempt. Without sudo the script leaves an interim nohup daemon. CI
surface documented in CLAUDE.md + docs-site ci.md.
