Phase 2 (systemd tag) notified per-service restart handlers and then
called meta: flush_handlers itself, so any run where either unit's
template content changed (including first apply) restarted BOTH
live services immediately in Phase 2 -- before Phase 3 firewall
scoping or Phase 4 smoke tests ran. This contradicted the phase's
documented purpose (units land on disk only, nothing starts/restarts
until Phase 4).
Fix: Phase 2 only reloads the systemd daemon and registers each
template task's changed result. Phase 4 (verify.yml) now decides
start vs restart per-service based on that recorded change, so
restarts remain independent per instance and never fire before
Phase 4.
