"""
|

TransferRenameBuild 事件的单元测试。
|
||
|
||
通过 patch ``eventmanager.send_event`` 模拟链上插件处理器，避免依赖
|
||
MoviePilot 的"插件实例反查"机制（``__get_class_instance`` 要求 handler 位于
|
||
``app.<plugin>`` 模块内）。覆盖以下关键路径：
|
||
|
||
1. 插件就地 mutate ``rename_dict`` 后，主程序首次渲染读取到补充字段；
|
||
2. 插件用"返回新 dict"的方式（替换 ``event_data.rename_dict`` 引用）也能生效；
|
||
3. 没有任何监听者时（``send_event`` 返回 None），渲染输出与改造前完全一致；
|
||
4. ``get_rename_path`` 把正确的 ``source_path`` / ``source_item`` / ``template_string``
|
||
注入到 ``TransferRenameBuildEventData``，便于插件做条件早退。
