Keep persist_pg_consensus_read_committed off wherever consensus is backed by CockroachDB, where the CRDB_* queries are only linearizable under SERIALIZABLE and persist asserts on the connection isolation level: * crdb-restarts points environmentd at CockroachDB via a manual consensus URL, so signal metadata_store="cockroach" to force the flag off. * The maelstrom workloads no longer hardcode READ COMMITTED. A new --consensus-read-committed arg (default off) lets the persist harness enable it only for the vanilla Postgres consensus variant.
