Records each checkpoint run with started_at, finished_at, duration_ms, status (success/failed), and error message. Queryable via `SELECT * FROM system.checkpoints`. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- TestCheckpointerRunRecordsSuccess: verifies row insertion with correct column values (status, timestamps, duration) and accumulation across runs - TestCheckpointerRunRecordsFailure: verifies run() handles INSERT errors gracefully without panicking (read-only DB) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Without a readiness probe, `kubectl wait --for=condition=available` returns as soon as the container starts — before the control plane connects to the config store and runs AutoMigrate. This causes a race where the seed SQL runs before tables exist, failing with "relation duckgres_managed_warehouses does not exist". The /health endpoint on the admin port (9090) only becomes available after SetupMultiTenant completes (config store connected, tables migrated, admin server listening), making it an accurate readiness signal.
