-Need a local CockroachDB to point the agent at? The repo ships a helper script that provisions a local multi-node insecure cluster on `localhost`:

-```bash
-./scripts/setup-cockroachdb.sh start     # start the cluster
-./scripts/setup-cockroachdb.sh status    # show running nodes
-./scripts/setup-cockroachdb.sh stop      # stop nodes (data preserved)
-./scripts/setup-cockroachdb.sh destroy   # stop and remove all data
-./scripts/setup-cockroachdb.sh --help    # all options (--nodes, --version, --port, ...)
