Separate real group role from title in serialized name card

A custom special title (e.g. a troll "群主" given to a regular member)
used to override the permission-based role, misleading the LLM about
who actually holds authority. Now the real role (群主/管理员/群员) from
member.permission is always shown, with the title slot showing the
special title (labeled 头衔"…") when present, otherwise falling back to
the activity-level temperatureTitle that everyone sees in chat.
