When GalaxyRepository.ExtendedAttributes is true, uses the extended
attributes query that includes both primitive (system) and dynamic
(user-defined) attributes. Default is false (dynamic only, preserving
existing behavior). Extended mode returns ~564 attributes vs ~48.
Adds PrimitiveName and AttributeSource fields to GalaxyAttributeInfo.
Includes 5 new unit tests and 6 new integration tests covering both
standard and extended attribute modes.
