Add --ft-non-retryable-exception-file to mark nodes unhealthy when workers fail with specific exception patterns (e.g., config errors). This prevents retrying on errors that won't be fixed by retrying. Implementation: - Workers write full tracebacks via sys.excepthook to error files - Launcher checks error files against configured patterns on worker failure - Nodes with matching exceptions increment unhealthy_count and exit - Rendezvous uses unhealthy_count to decide if job can continue Example: Configure patterns like "insufficient shared memory (shm)" to stop retry on configuration error.
