Migration 022 adds agent_hosts / game_instances / instance_clusters /
instance_stats (named agent_hosts to avoid the existing B2B hosts
table). HostAgentConsumerService now parses the full v2 heartbeat and
upserts an agent_hosts row (host metrics: cpu/mem/disk/agent version,
keyed by license_id+hostname until enrollment) plus one game_instances
row per heartbeat instance entry (state + uptime, the billing unit).
Legacy server_connections write retained so the current panel keeps
working — additive migration, nothing breaks. Staleness sweep + offline
beacon now flip agent_hosts too. cluster_id FK reserved for Soulmask/
Dune. Migration applied to live DB; tsc green.
