The small GitHub runner shape (AWS, 72G root) ran out of disk in swarm and compose rows (#1329: WordPress#2 of run 41261531965, Nextcloud#6 and #7 of run 41262286962) while an empty instance-store disk nvme1n1 sat unused. mount_spare_disk.sh formats and mounts it at /mnt, but only on a GitHub-hosted runner outside act, and only a whole unpartitioned disk without any signature, mount or swap use of at least 75G; every decline leaves a notice. relocate_docker_dataroot.sh then bind-mounts /var/lib/containerd from the spare disk and moves the Docker data-root to /mnt/docker-host (not /mnt/docker, which is the nested daemon's volume that dedicated.sh wipes). It refuses before stopping anything when images, volumes, build cache, foreign containerd namespaces or shims exist or daemon.json is unreadable, and rolls back the bind mount and daemon.json on any later failure or cancel. Swap goes on / once containerd lives on /mnt, dump_state.sh logs disk size, model and free space per storage root, and the swarm watchdog samples / and /var/lib/containerd every 10 s.

Brings in 225 commits, including the merged web-app-openbao work and the
LMStudio loopback fix.
Seven conflicts:
- The legacy svc-net-wireguard-core/plain/firewalled roles this branch deleted
in e706170a0 were modified upstream. The deletion stands, which is the whole
premise of the branch.
- The MCP audit takes upstream's list plus svc-net-firewall, with the three
legacy wireguard entries collapsed into the single svc-net-wireguard: 23.
- web-app-openbao/README.md takes main's reviewed version wholesale.
- matrix.py takes both sides: upstream's app_id argument to _reset_credentials
and this branch's _write_mesh call after it.
The merge pushed matrix.py to 511 lines against the 500 cap, so the step
runner moved to utils/tests/swarm/run.py, which is self-contained and leaves
matrix.py at 427. Its test moved with it.
