Problem mz_catalog.mz_indexes is a BuiltinTable whose rows are written by pack_index_update. This requires coordinated writes from a single environmentd process, which conflicts with the multi-envd goal. Solution Convert mz_indexes to a BuiltinMaterializedView backed by a query over mz_internal.mz_catalog_raw. Testing Updated tests to reflect that mz_indexes is now a MATERIALIZED VIEW
