(n): int = 1 is valid Python, but the native parser rejected it: the annotated assignment rule only accepted a bare name or an attribute/subscript target before the colon. CPython's grammar also allows '(' single_target ')' there, and the rule even carried a TODO about the missing clause.

Add that alternative, with a parser test and a roundtrip fixture.

Fixes #1011
