- Use sqlb.set() instead of set_str() for boolean is_fileset field
to avoid quoting (SET is_fileset = TRUE not 'TRUE')
- Add JSDoc comment to isFilesetResource explaining it matches
children inside .fileset/ directories, not the directory itself
- Update OpenAPI spec for file_resource_type_to_file_ext_map endpoint
to document the new response schema with format_extension and
is_fileset fields
