A lost stream or a failed Enter write returned without killing the
in-container gh, leaving it polling with a temp GH_CONFIG_DIR that would
receive the token. The output loop is now drive_login (generic over the
stream, writer and emitter, so it is unit-tested without Docker), and
its result goes through cleanup_on_error, so every ending except a token
read back runs the pkill. Neutral wording for the shared ANSI stripper's
overflow warning.
