No Config Debugging errors when multiple vscode windows are open

If I use the no config debugging feature with multiple vscode windows open, all of them try to start debugging. Whichever is first suceeds and the rest throw a Server[pid=xxxx] is already being debugged error.

The cause for this is that the extension watches the .noConfigDebugAdapterEndpoints dir and starts debugging if any file appears in it not just if the specified file (VSCODE_DEBUGPY_ADAPTER_ENDPOINTS) is created. Each window has a separate endpoint file in the .noConfigDebugAdapterEndpoints dir, but due to watching for any file, every window will start debugging.

從 src/extension/noConfigDebugInit.ts 第 95-97 行附近開始，閱讀 .noConfigDebugAdapterEndpoints 目錄是如何被監視的。確認只有在建立了由 VSCODE_DEBUGPY_ADAPTER_ENDPOINTS 指定的端點檔案時才會開始偵錯，從而使彼此獨立的 VS Code 視窗不會對對方的檔案作出反應。
