The crontab is copied verbatim to every load balancer, so each LB ran the
same cluster-wide work against MAIN's database: the retention DELETEs on
lines_activity/lines_logs/login_logs/streams_errors/streams_logs/
ondemand_check, the TMDb and TMDb-popular crawls, the purge of every node's
signals, the GitHub update check that rewrites settings.update_data, and
the marketplace check for module updates (modules are MAIN-only).
Add XcVm\Core\Cluster\NodeRole::isMain() (Phase 0 of the MAIN <-> LB API
plan; the node mode and flow bits land there later) and gate each of those
on it. An unknown answer reads as "not MAIN", so a node that cannot tell
skips one run instead of doing cluster-wide work. Per-node work (local
stream and archive cleanup, this node's certbot, this node's own signals)
is unchanged.
