Emil SimeonovandDevin <158243242+devin-ai-integration[bot]@users.noreply.github.com> e32ba51a7d fix: pre-configure daemon.json before rootless setuptool + add DBUS_SESSION_BUS_ADDRESS
Five fixes for rootless Docker setup on Arch Linux runners:

1. Write daemon.json (with containerd-snapshotter: false) BEFORE running
   dockerd-rootless-setuptool.sh, so Docker 29 starts with overlay2 from
   the very first boot instead of containerd snapshots.

2. Add DBUS_SESSION_BUS_ADDRESS to all systemctl --user tasks. Without it,
   systemctl --user fails with "Connection refused" on Arch Linux where
   the D-Bus session bus isn't auto-discovered.

3. Fix pre-configure override port driver: use 'builtin' for slirp4netns
   and 'implicit' only for pasta. The previous unconditional 'implicit'
   caused dockerd to exit immediately on slirp4netns hosts.

4. Fix prune timer schedule from '*-* * */6:00:00' (invalid) to
   '*-*-* 00/6:00:00' (every 6 hours, valid systemd calendar spec).

5. Add explicit Docker 29→28 downgrade task for Debian/Ubuntu using
   version-pinned apt install with allow_downgrades.

Closes GRM-158
