fix(loop.py): Remove OUTPUT_IS_LIST to enable automatic unwrap in ComfyUI

The `OUTPUT_IS_LIST = (True, True, True, True, True)` assignment in `AutoLoopCalculatorTTSBatch` was preventing ComfyUI from automatically unwrapping 1-item lists, causing downstream nodes to crash with TypeErrors (expecting raw strings/integers but getting lists). By removing this attribute while keeping `INPUT_IS_LIST = True`, ComfyUI can now safely process inputs as batches while unwrapping and forwarding primitive values to the next nodes.
