在mac arm64上无法打开 "Manage Models"

核心问题已确认：NSPopUpButton 在 _refresh_model_manager_content

方法中作为局部变量使用时未定义。这是一个典型的 Python 变量作用域 bug。

No response

Start in menubar_app.py at _refresh_model_manager_content, called by _build_model_manager when Manage Models is opened. Reproduce the action on macOS arm64, inspect the traceback around line 1151, and verify that Manage Models opens without the reported UnboundLocalError.
