feat(objects): ExtractProperties — [CommandProperty] props with enum expansion

Add ObjectIntrospection.ExtractProperties(Type) to extract public instance
properties carrying [CommandProperty] attribute, including inherited ones.
Properties include type via ObjectNaming.FriendlyTypeName, read/write access
levels, readOnly flag, and enum values expanded via Enum.GetNames.
