Add detection for third-party addon FileHandlers to prevent conflicts by @Clonephaze in https://github.com/mika-f/blender-drag-and-drop/pull/129
这是 Blender 软件运行 Python 脚本时的报错信息，核心内容为：
错误类型：AttributeError（属性错误 ），调用 bpy.ops.import_mesh.threemf 操作符时，该操作符无法找到 。
报错回溯：
- 先在路径 C:\Users\luke1\AppData\Roaming\Blender Foundation\Blender\4.5\extensions\blender_org\drag_and_drop_support\formats\_3mf.py 的第 48 行 execute 函数里，尝试执行 bpy.ops.import_mesh.threemf() 。
- 接着在路径 D:\Program Files\Blender Foundation\Blender 4.5\4.5\scripts\modules\bpy\ops.py 的第 109 行 __call__ 函数中，执行 ret = _op_call(self.idname_py(), kw) 时出现问题 ，最终报错 AttributeError: Calling operator "bpy.ops.import_mesh.threemf" error, could not be found ，即找不到 bpy.ops.import_mesh.threemf 这个操作符，可能是相关功能未正确加载、插件缺失或版本兼容问题等导致 。
Great add-on! For some reason, it doesn't work in 5.0. Any ideas?
