 Fix: accumulate OAuth scopes on 401/403 instead of overwriting
 
-When an HTTP transport receives a 401 or 403 with a `WWW-Authenticate` header
-containing new scopes, the scopes are now merged with any previously-acquired scopes
-rather than replacing them. The previous behaviour could cause an infinite re-auth loop
-where the client repeatedly lost its original scopes each time it attempted to upscope.
