Jira issue: CRDB-67206

Start by running kv/kvserver_test.TestSnapshotHardlinkFailureAborts, then read pkg/kv/kvserver/client_snapshot_manifest_test.go and the installTestManifestForKey helper in client_basalt_manifest_helpers_test.go. Use the linked test report and stack trace to trace the failure through replica_manifest_committer.go and rs_engine_testing.go. Done means the test passes reliably on the reported race configuration without leaving test logs behind.
