When index.query.default_field is '*' and the index mode is strictly columnar, SearchExecutionContext#defaultFields() now expands the wildcard to only those fields that are indexed (isSearchable() == true) and are not metadata fields. This prevents query types such as query_string, simple_query_string, and multi_match from inadvertently targeting non-indexed columnar-only fields by default.
