Kysely's Migrator checks for its tables via introspection.getTables(),
which reflects every schema and calls has_schema_privilege /
pg_get_serial_sequence per schema. When another test file drops its schema
at the same moment those functions fail with "schema … does not exist" —
the intermittent server PG test failures on the shared dev database.
createMigrator now hands the Migrator a proxy whose introspection only
looks at the migration schema (or current_schema()). A regression test
churns schemas while migrating; it fails on the old migrator.
Also samples EngineRunQuery's comma-separated status/triggeredBy in the
contracts schema test.
