Use the real hive column name (`drone`) in the prototype's live query
and pin the Grafana datasource uid to `swarm-prom` so provisioned
dashboards resolve their Prometheus source in k3d.
Ansible provisions the k3d cluster and Flux controllers; Terraform
modules deploy the simulated fleet and ground warehouse. Compose and
k3d share var/t1 (live lake) and var/t3 (warehouse). The prototype
gains a live mode fed by the explorer read-only SQL API.
