deploy/README.md still described the deleted managed-global overlays as
the second overlay surface. Replace with a description of script
overlays (bubblewrap + systemd-run sandbox, resource caps).
Full test sweep: 367 passing, 2 skipped across l4d2web, l4d2host, deploy.

deploy-test-server.sh: provisions the l4d2-sandbox system user (no home,
nologin shell) and installs the bubblewrap apt/dnf package; copies the
left4me-script-sandbox helper into /usr/local/libexec/left4me with mode
0755. Drops the global_overlay_cache directory provisioning, the
refresh-global-overlays unit installation, and the timer enable.
Deletes the orphaned left4me-refresh-global-overlays.{service,timer}
files. Trims the matching paragraph from deploy/README.md.

Drop MountFlags=shared (the assumption that it propagated fuse mounts
to host was incorrect on systemd 257 with ProtectSystem+ReadWritePaths).
Restore PrivateTmp=true (was dropped in 593611e for fuse propagation
that did not work). Rewrite the comment block to describe the new
model: mounts go through the left4me-overlay helper which nsenters
into PID 1's mount namespace, so the unit's mount-ns layout is no
longer load-bearing.
Update the three user-facing READMEs (root, l4d2host, deploy) to drop
fuse-overlayfs / fusermount3 prereqs and call out the kernel overlayfs
mount path through the privileged helper.

The workshop + managed-global overlay surface fully covers the
admin-SFTP flow that 'external' was a placeholder for. Drop the type
from the model defaults, builder registry, routes, template, and
tests, and add migration 0004 that deletes any leftover external
rows along with their blueprint and job references.

Adds two managed system overlays (l4d2center-maps, cedapug-maps) that
fetch curated map archives from upstream sources and reconcile addons
symlinks for non-Steam maps. A daily systemd timer enqueues a coalesced
refresh_global_overlays worker job; downloads, extraction, and rebuilds
run in the existing job worker and surface in the job log UI.
Schema: GlobalOverlaySource / GlobalOverlayItem / GlobalOverlayItemFile
plus nullable Job.user_id so system jobs render as "system" in the UI.
The new builder reconciles symlinks against the per-source vpk cache
and leaves foreign symlinks untouched. Initialize-time guard refuses
to mount a partial overlay if any expected vpk is missing from cache.
Refresh service uses shutil.move to handle EXDEV when /tmp and the
cache live on different filesystems.

Adds /var/lib/left4me/workshop_cache to the deploy mkdir list (owned by
the left4me runtime user). Updates deploy/README.md to document the new
directory and the workshop overlay layout: web app downloads VPKs into
the cache and symlinks them into overlays/{overlay_id}/left4dead2/addons/.
