  * Used only for local testing — on real Tdarr this file comes from the server.

  * Matches the real Tdarr CLI constructor signature:
- *   new CLI({ cli, spawnArgs, WorkDir, jobLog, inputFileObj })
- * inputFileObj is accepted but unused here (only used by real Tdarr for progress tracking).
+ *   new CLI({ cli, spawnArgs, WorkDir, jobLog, inputFileObj, updateWorker })
+ * - inputFileObj : used by real Tdarr for ffprobe-based progress tracking
+ * - updateWorker : callback used by real Tdarr to push progress to the UI
+ * Both are accepted but unused here (local mock just logs to stdout).
