Switching from Elastic Cloud to OpenSearch
Pull `opensearchproject/opensearch:2` and `opensearchproject/opensearch-dashboards:2` via the official docker-compose. Elasticsearch indices through 7.10.x are wire-compatible with OpenSearch — use the OpenSearch upgrade tool or `_reindex` from a snapshot. Above 7.10 (8.x), use cross-cluster `_reindex` from Elastic Cloud → OpenSearch over HTTPS. Kibana dashboards port to OpenSearch Dashboards with minor JSON edits.
