// Patches vscode-unity-debug's UnityProcessDiscovery.GetUnityEditorProcesses to
// prefix-match process names instead of requiring an exact "Unity"/"Unity Editor".
// The comparison is OrdinalIgnoreCase, so the "Unity" prefix then matches editors
// launched directly ("Unity") and via Unity Hub ("unityhub-unity-editor-<version>").
// Extra matches (UnityPackageManager etc.) are fine: with a config name containing
// "Editor", the adapter picks the editor by process_id from EditorInstance.json.
