Jira issue: CRDB-68411

Start with the failed TeamCity artifacts and CockroachDB logs, focusing on pkg/pebble/version_set.go:456 and the MANIFEST flush error. Read pkg/cmd/roachtest/README.md and the linked investigation guidance, then use the Grafana and roachdash links to compare the failure; done means identifying and resolving the unsupported protocol-version failure so this roachtest passes.
