load_manifests() only ran at startup, so a manifest published via the
signed catalog sat dormant until the next service restart (found while
shipping the strfry manifest fixes: package.check-updates refreshed the
cache but the orchestrator kept rendering the old overlay).
- refresh_catalog now reports whether the cached bytes actually changed
(write_cache skips identical rewrites), so unchanged hourly polls
don't churn the manifest map.
- New ContainerOrchestrator::reload_manifests (default no-op); prod
delegates to load_manifests — the rebuild is atomic under the state
write lock, and the reconciler's durable user-stopped/uninstalled
marker filters make a mid-session reload equivalent to the restart
path that already runs on every boot.
- package.check-updates reloads on change and reports catalog_changed +
manifests_reloaded; the hourly update-scheduler tick (and its startup
refresh) do the same.
Tests: app_catalog 5/5 (new write_cache changed-detection test),
reconcile 16/16, knows_app 1/1.
